Do-it-yourself spoiler making step by step. Brief step by step instructions

Installing a spoiler on the trunk is the dream of every second motorist. This product is suitable for any car model, making its exterior more sporty and dynamic. It is known to many under the name "wing", and outwardly resembles a goal in football.

The do-it-yourself “wing” installed on the trunk will perform a lot of useful functions, namely:

improve the aerodynamic qualities of the machine;
improve stability and control, especially when cornering;
change the properties of the air flow;
prevent dirt from getting on the glass of the car.

Spoiler improves stability and handling, especially when cornering

Most often, the device is placed on the back door or on the luggage compartment lid, but the front spoiler is not uncommon, which performs the same functions as the rear one. It does its job more effectively when the car accelerates to 80 km / h. There are a lot of drawings on the do-it-yourself spoiler on the network, and the decision on what shape and size the tuning element will have, its location - rear or front, is up to you.

Creation

Having learned about the good aerodynamic properties of this tuning element, many drivers are wondering how to make a spoiler with their own hands.

To get started, find a diagram on the Internet on how to make a tuning element yourself. Arm yourself with cardboard and a pencil, make a drawing on it, so that later it would be convenient for you to cut out the components of the product according to the template.

Spoiler Mounting Diagram

To make a spoiler for a VAZ 2114 or any other car, you will need:

foam plastic 1m x 1m with a thickness of 50 mm;
car enamel to match the color of the car;
steel sheet with a thickness of not more than 15 mm;
putty and primer (2-3 cans);
epoxy glue (up to 2 kg) with brushes for application;
ruler or tape measure;
sandpaper with different grain sizes;
fiberglass (carbon fiber);
LEDs (optional)

The principle of how to make a spoiler for a Gazelle Next is the same for any car and involves the following work:

Using foam, cut out the future sharp part of the spoiler according to the prepared pattern. Do this diagonally so that the size of the product matches the required.
Make fasteners for the tuning element. To do this, cut out plates from a steel sheet, drill 3 mm holes in them at a distance of no more than 30 mm. Next, bend the plates in the shape of the letter L - this way it is convenient to fix the plates. As a basis for the visor, install nuts with a diameter of 6 mm. Glue the nuts to the foam blanks and cover with fiberglass, applying it in 2-3 layers. After gluing each layer, wait for the composition to dry, and then apply the next one to successfully polymerize the adhesive. For the same reason, do not prepare a lot of glue at once - knead it as you apply it. To wash off the composition, hot water is enough. To prevent the build-up of static electricity, which is typical for small pieces of foam when cutting, contact with grounded surfaces during operation.

If there is a brake light or other optics in the rear spoiler, lay the wiring inside in advance and install the backlight.
Apply primer and putty to the surface to level it. Sand the product with fine-grained sandpaper in preparation for staining.
Apply car enamel from a can or use a brush on the workpiece.
The next step in how to make a spoiler on a VAZ is applying varnish to the workpiece. Before varnishing, treat the surface with a degreaser.

After you managed to make a fairing, install it on a pre-prepared place on the body.

Many motorists believe that the highlight of a car is a spoiler.

Thanks to him, the car looks stylish and original, as it correlates with the exterior of the car, determining its appearance, and having a bearing on the design. This is its aesthetic function. A synonym for a spoiler is a wing. It looks like a football goal.

In general, this is an additional element for a car that performs a number of positive functions. Firstly, it improves the dynamic properties of the car, radically changing its appearance.

It is also necessary to increase the stability of the machine and achieve optimal control, being at the same time a certain load on the front and rear of the body. Secondly, the spoiler changes the characteristics and movement of the airflow.

These are its main features that make it so popular. The presence of a spoiler on a car indicates that the car takes turns more confidently, eliminating the possibility of damage during skidding, increasing braking efficiency. It also eliminates the ingress of water and all sorts of dirt on the car windows.

It is quite capable of fulfilling the tasks assigned to it when the speed of the car reaches 80-90 km / h. Mount the spoiler either on the back door or on the trunk. True, there are other options.

1. Types of spoilers

Spoilers are of different types. They are created by hand, however, in most cases they are manufactured at the factory. Then this is mass production, which concerns a specific model of car. The spoiler is installed on the car by the manufacturer.

It is customary to distinguish between the following types of spoilers:side, those that are mounted on the bumper, there are roof spoilers and a rear spoiler. Side spoilers are door sills. In the people it is customary to call them thresholds-overlays. Spoilers that are designed to be mounted on the bumper are popularly called bumper skirts. They are usually installed at the bottom.

Those spoilers that are installed on the roof of a car are usually found on crossovers and hatchbacks. They are attached to the top of the back door. The rear spoiler is installed on sedans, on the trunk lid.

There is such a kind of spoiler, which is installed on hatchbacks, where the back of the car has a gentle angle. For example, this VAZ-2108. Here it is possible to install a rear spoiler below the rear window. All of them differ in design and material for the manufacture of the spoiler.

2. How to choose a spoiler?

In the process of choosing a spoiler, it is necessary to take into account its functional purpose. The fact is that his right choice can affect the aerodynamics of the car body, while being an ornament.

Branded spoilers have better characteristics, so you need to buy a good model for the appropriate price. Spoilers should be installed by professionals.

3. How to make a spoiler yourself?

It turns out that the spoiler can be created by hand. This requires durable material and other improvised means.

- foam, the size of which is 100x100 cm, and the thickness is 5 cm;

Paint that matches the color of the car - several cans are needed;

Sheet of iron, the thickness of which is not more than 1.5 mm;

Primer and putty - three jars;

Epoxy glue within two kilograms;

Brushes for applying glue;

Ruler;

Sandpaper;

Carbon fiber or fiberglass;

neon lights;

LEDs;

The very principle of creating spoilers is the same. Its specificity of work and functional purpose correlates with the right choice.

Brief step by step instructions

1) First you need to use the foam to cut out the "blade" of the wing. It is better to do this diagonally, because in this way it is necessary to keep within the dimensions.

2) The next step is the manufacture of the mount. Plates are cut from a sheet of iron. Next, you need to drill three millimeter holes. The distance between them should be no more than 30 mm. At this stage of work, we bend the plate in the form of the Latin letter L, since this is how it is convenient to fasten.

Nuts with a diameter of 6 mm are welded into the base. Then they are carefully glued to the foam blanks and pasted over with carbon fiber (fiberglass). At least three layers of fiberglass must be applied. During pasting, it is necessary to maintain an interval. This is necessary in order for the glue to polymerize.

To speed up the process, heat the glue a little. There is no need to immediately prepare a lot of glue, since there will be no large consumption, and it will quickly harden. It washes well under running hot water. Styrofoam crumbs have the property of sticking. To remove static electricity, you must touch grounded objects.

3) In the event that you decide to make side lights or a brake light, you need to put the wires in the glued spoiler, installing LEDs and neon lights.

4) At this stage of work, we prime the surface. Then we apply putty, clean it with sandpaper and prepare for painting.

5) Painting the resulting workpiece.

6) The final stage is varnishing the spoiler. At the time of installation of each new part, a degreaser must be used.

7) The surface of the spoiler must be put in order.

8) We install the spoiler in the previously prepared place.

Basic materials

The spoiler is usually made of metal. Aluminum works well. Racks are usually made from it. Sometimes steel and carbon are practiced. Nowadays, metal spoilers are quite rare.

The most common material for its production is fiberglass. It is based on synthetic resin. It is cheap and very easy to handle. Its positive quality is good strength.

There are also spoilers made of ABS plastic. This is a cheap material. Use it as a result of mass production of spoilers. This plastic contains various impurities, so it is light. However, a plastic spoiler is not durable, as it becomes quite brittle over time.

Appeared not too long ago silicone spoilers and silicone polymers. They are popular due to ease of processing, good service life and excellent ductility.

It is customary to consider those spoilers that are made of carbon fiber to be very expensive. The weight of this material is small, the strength indicators are excellent. The manufacturing process is labor intensive. To create a bulge of the roof, a curved chipboard guide is used.

Coloring

To paint a spoiler, you do not need to have special skills. This can be done independently and even in a garage. Initially, the spoiler is prepared for painting by wiping with a solvent. Thus, the transport soil is removed. Next, sandpaper is used.

Thanks to it, the entire surface becomes matte. Particular attention must be paid to folds and corners. Then we apply primer and paint, checking the cleanliness of the surface before that. Paint is usually matched to the color of the car. It is applied in thin layers. There must be several. A high-quality coating requires five to six stages of painting, since after the first pass there will be no even layer.

When the paint is completely dry, the spoiler is varnished using a special spray can containing varnish. Check the spray can on the test surface, shaking before that for three minutes. Lacquer is also applied in the amount of approximately five layers, between which the drying of each subsequent one.

To improve the appearance of the car, the market offers various tuning elements, including a spoiler. The spoiler will make the car more attractive, give it positive driving characteristics. You can make such an accessory with your own hands, giving it the desired shape. Do-it-yourself work does not require expensive materials and special tools.

What is a spoiler on a car

A spoiler is one or more special elements designed to change the aerodynamics of a car body by redirecting air flows. The main purposes of installing this part are as follows:

reduction of aerodynamic drag;
increase in downforce;
fight against pollution of a car body.

It is worth mentioning that many install a spoiler as a decorative (tuning) element. Its fastening can be done in front, behind, on the roof or on the side of the car. With an individual approach, you can make a spoiler to order, which will allow even a serial car to stand out in the traffic flow.

Pros and cons of installation

The spoiler gives the car the following qualities:

attractive appearance;
improved dynamics;
increased adhesion to the canvas;
reduction in fuel consumption;
improving braking efficiency.

It should be clarified that the positive qualities of the element in question appear at speeds above 100 km / h.

The disadvantages include:

high cost of structural elements;
increase in fuel consumption with an incorrectly selected form or installation;
fragile material of manufacture (plastic).

Auto tuning options

Today you can pick up a spoiler for almost any car, regardless of body type: from a sedan to a minibus. To make the choice easier, you need to understand in more detail by what criteria this tuning element is classified:

at the place of installation;
according to the installation method;
by material;
in form.

The main installation location of the spoiler is the rear of the roof or the trunk lid. It depends on the body type, as well as the size of the spoiler and its shape. You can attach a tuning element:

using double sided tape. The option is appropriate for small spoiler sizes;
bolt fastening. Many motorists do not like this method because of the need to make holes in the body part;
fastening with brackets. The option is suitable for those cars that have a certain shape of the rear cover and a gap between the body.

What material is suitable for tuning

As for the material for the manufacture of the spoiler, the most common are:

ARB plastic;
ordinary plastic;
fiberglass;
polyurethane;
aluminum.

In order to give preference to the construction of one or another material, it is first necessary to consider each of them in more detail, taking into account its chemical and technical characteristics.

Which shape to choose

Spoilers can be quite varied in form. To conclude whether this option is suitable or not, the part must be seen in front of you. There are cases when the shape of the element complements the part of the body, but basically the spoilers are represented by the most non-standard designs. With their help, you can give the car not only exclusivity, but also aggressiveness.

Spoilers can also be classified by design:

Rules for selecting a suitable spoiler

Today, many spoilers are produced for a specific car brand and model, but there are also universal options that are suitable for almost any car. The only difference is where they will be attached. The car itself should also be taken into account: if we are talking about the executive class, then the spoiler will obviously be an extra element in the design.

It is important to evaluate how the chosen accessory will look. To do this, just take the part, attach it to the car and see from the outside how it fits with its appearance. Many tuning studios have a special program with which you can choose the best option, after which they determine the installation location of the element. If the spoiler is designed for a specific car, then this question does not arise.

It is better to purchase a spoiler without a paint layer, which will allow you to find the color that matches the car. An important point is the selection of a suitable mounting method.

In order not to make a mistake with the choice, it is better to contact only reputable tuning companies. Only in such studios you can install really high-quality products.

When choosing a spoiler, attention should be paid to the material: in many cases, the part is made of plastic, which is characterized by both low cost and short service life. The plastic spoiler under the influence of sunlight quickly burns out and breaks with minor impacts.

In addition, there is such a material as fiberglass. The part made from it rather quickly loses its original appearance and fails.

Carbon products are of better quality and, accordingly, more expensive. It is important to understand that a high-quality spoiler should be made for a specific brand and model of the car, taking into account the improvement of its aerodynamic characteristics. Therefore, one can only say about universal options that the level of their quality is questionable.

How to make a spoiler for a car with your own hands

When and why do you have to ask yourself the question of making a spoiler yourself? Today, a large selection of the element in question is offered and, it would seem, it is not required to do something with your own hands in this regard. But then the cost of a quality spoiler turns out to be quite high, and this indicator is not a guarantee that the desired effect will be achieved.

Therefore, some car owners design spoilers on their own, getting the desired design and the desired effect from installing such an element. A homemade accessory can be made using various materials that the owner chooses based on his imagination and free time.

Tools and materials

To start making a spoiler, you will need to prepare the following list of materials and tools:

foam sheet;
fiberglass about two meters;
fixings and welding;
paint in spray cans (2 pcs.);
primer (3 cans);
epoxy glue 2 kg;
brushes;
spatulas;
mesh for reinforcement;
sandpaper.

Depending on the specific design of the product, the main material is:

gypsum;
Styrofoam;
mounting foam;
metal carcass.

Stages of making a homemade spoiler

The whole process of creating a structure can be divided into several stages:

mold making;
material reinforcement;
putty;
painting;
installation.

It is best to use cardboard as a template. You can also use plywood, but this will lead to additional costs.

Regardless of the material chosen, after implementing the desired shape, be sure to try on the pattern on the machine. You need to make sure that the size is chosen correctly and the attachment points correspond to the intended places. You should make sure that the future product is symmetrical, for which the pattern is bent in half.

The frame can be made from different materials, but its main role is to keep the given shape at the beginning of the part manufacturing. The spoiler will be stiffened by fiberglass, as well as a layer of putty and paint. When choosing a filler, it is necessary to take into account the planned shape of the future product.

Making a spoiler from foam and fiberglass

One of the important steps in creating a spoiler is proper design. "By eye" this element can not be done. The ideal option at the design stage would be to involve an engineer or an experienced person who is engaged in this type of tuning.

After determining the dimensions and design, you can begin to create a metal frame.

Quite often, in the manufacture of the rear spoiler, a 1.5 mm thick galvanized iron sheet is used, the edges of which are bent upwards. M6 nuts should also be welded to the base for subsequent installation of the product.
The resulting frame is glued on all sides with foam blanks to increase the volume; mounting foam is also often used. The thickness of the foam is chosen at the discretion of the owner. You can cut it with an ordinary clerical knife or a metal sheet. The result is a matrix.
When the spoiler blank is ready, fiberglass (glass carbonate, fiberglass) is used to stiffen it. A minimum of three coats of material should be applied at short intervals to cure the resin. Each subsequent layer should be denser than the previous one. It is necessary to strive to ensure that there are no air bubbles between the layers. The last layer of fiberglass must be coated with polyester resin. If desired, a brake light can be mounted in the spoiler, then the wires should be laid precisely at the stage of pasting with fiberglass.
To obtain good adhesion, the surface of the product should be primed, after which putty is applied.
The next steps are to clean the surface with sandpaper, this will give the spoiler as even a look as possible.
At the final stage, the part is primed and covered with several layers of paint, and then varnished.

Step-by-step production of a plaster spoiler

With the help of a material such as gypsum, you can make not only a matrix, but also a copy of your favorite spoiler.

For pouring gypsum, we make a box of foam. Then we put the part matrix or the finished spoiler into it, after wrapping it in cling film to avoid damage.
Fill the box with plaster. After the material hardens, we cut it into two parts. After removing the original, we will receive an exact copy of the form.
To make a blank, we line the mold with a film and fill it with plaster.
After it hardens, open the halves of the matrix and take out the workpiece.
Subsequent actions are aimed at finishing, reinforcing and painting the spoiler.

To give the matrix strength, you should follow the same recommendations that are given for the manufacture of a foam spoiler.

How to make a foam spoiler at home

The procedure is simple, but requires care in order to avoid damage to the body coating.

We close the upper part of the trunk lid with polyethylene, you can also use masking tape.
We cover the prepared surface with mounting foam.
We are waiting for the foam to solidify, then we form the future part with a sharp knife.
In order to bring the product to the desired shape, you should use sandpaper.
We also add rigidity to the product through the use of fiberglass.
The final stages are similar to the previous methods for making an accessory.

The matrix can also be made from plasticine. The process is similar to the described sequence of steps for making a foam spoiler. Regardless of the method chosen, care must be taken to ensure sufficient rigidity of the structure. In addition, the fastening of such a tuning element should prevent its loss, ensuring reliable fixation.

Anyone can make a spoiler for their "iron horse" if desired. To do this, it is enough to select the necessary materials and tools. It doesn't matter which car is tuned - Niva Universal or Mercedes Benz ML. If you carefully follow the step-by-step instructions, the car can be made much more attractive, as well as significantly improve its technical characteristics.

Wanting to stand out from the gray traffic flow, each car owner comes up with ways to give his car a memorable appearance. Not everyone can afford to apply a drawing with an airbrush or completely tune a car. But to make a spoiler on the body with your own hands is a task available to the owner of any car model. Such tuning not only ennobles the exterior, but also gives the car improved aerodynamic characteristics.

What is a spoiler for a car

In a car, a spoiler is a separate element that redirects air flow to reduce the aerodynamic drag of the body. In addition, the spoiler helps to fight the dustiness of the body and increases the downforce of the car while driving. In other words, the spoiler is able to give some types of cars additional sportiness.

What are spoilers for?

If we talk about the functions of modern spoilers, then we can distinguish three main purposes of this element:

giving the car additional acceleration - depending on the type of spoiler, the car can really get increased downforce and increased aerodynamic characteristics;
dirt repellency - spoilers prevent suction of dust and dirt from the road from under the bottom of the car;
decorative - it must be emphasized that most car owners install a spoiler solely for the sake of giving a sporty look to the car.

Depending on the quality of the product and the skill of its installation, amazing results can be achieved: the car will receive enhanced grip on the road surface, the air flows while driving will be redirected taking into account the direction of the car, due to which it can noticeably accelerate.

However, there are downsides to using spoilers. If the installation of the factory element has clear regulations and is carried out exclusively by professionals, then the car owner may not worry about the quality of installation and the functionality of the spoiler.

However, in cases where an inexperienced master (or car owner) tries to install a spoiler on a car on his own, it is unlikely that the desired effect will be achieved. With an illiterate installation of the spoiler, it will not be possible to use oncoming air currents, most likely, the car will experience additional difficulties when driving.

The spoiler is able to give the body a special finished stylish look.

Types of tuning elements

It would seem that a spoiler is a highly specific element for a car. However, there are several types of spoilers, each of which stands out depending on the style, location on the car body or material.

Variations in style

There are only two types of spoiler styles in the world:

factory - these are products that are produced by the largest manufacturers of elements for car tuning, as well as home-made spoilers that are outwardly identical to factory products. As a rule, such elements have a classic appearance and are suitable for installation on most car models;
individual - this type of spoiler includes factory spoilers, released in limited quantities, and home-made products. However, there is a significant difference in shape, color and proven aerodynamic properties. Not always individual style guarantees giving the car additional acceleration.

Differences in location on the car body

There are four types of spoilers according to their location, while the most common of them is the rear spoiler. It is mounted on the trunk lid.

The rear spoiler is especially popular with Russian drivers.

Roof spoiler - an option for advanced jeepers

The third place in the field of giving the car special aerodynamic properties is immediately divided by two types of spoilers that are mounted on bumper skirts or on side skirts.

Spoiler on the front bumper skirt gives the car a sporty look

Varieties by type of material used: photo

Modern spoilers can be made from a variety of materials. The main criterion is the strength and lightness of the product, as well as its wear resistance. Therefore, spoilers are made mainly from this raw material:

fiberglass (or, as it is also called, fiberglass). According to its composition, this substance belongs to plastic materials that are produced with the addition of synthetic resin additives and fiberglass. Today, fiberglass spoilers are considered the most budgetary in the car tuning industry. However, the low price does not affect the quality of the product in any way: a fiberglass spoiler has the same strength and durability characteristics as more expensive counterparts;

Spoiler made of fiberglass is characterized by low cost and a sufficient period of use

ABS type plastic. By itself, this type of plastic is quite fragile, therefore, in the manufacture of spoilers, various reinforcing additives and impurities are added to it. Due to their low cost, ABS plastic spoilers sell well, but their wear resistance leaves much to be desired;

Spoiler made of ABS plastic is relatively cheap, but it is fragile

silicone materials. The production of spoilers for cars from silicone began relatively recently. The great advantage of such products can be considered their elasticity and increased durability, since air flows, even during long-term operation, cannot deform such a spoiler;

Spoiler made of silicone materials is elastic, durable and attractive in appearance

carbon (or carbon-fiber material) is one of the most modern raw materials from which a spoiler can be made. The product will give the car excellent aerodynamic characteristics, but the cost of carbon spoilers is quite high;

A carbon fiber spoiler is quite expensive, but the envious glances of other car owners more than compensate for this small drawback.

light metals - aluminum and steel. Making a whole spoiler from metal is unprofitable and pointless, therefore, light types of metals are used only for casting individual elements - blades, racks and flaps.

Metal spoiler - an option for good cars and real men

The principle of the spoiler

Depending on the type of product, the principle of its operation will also differ. So, located on the trunk lid, the spoiler pumps air pressure over the trunk and rear glass. If there were no spoiler, then air rarefaction would form in this place, which directly affects the downforce of the car, reducing it. The rear spoiler increases the resistance of the air flow and thus allows the car to increase downforce, that is, grip with the road surface.

In addition, the rear spoiler, due to its location, relieves the air pressure created under the car body, which also increases the aerodynamics of the car.

If a skirt is located on the body and it is mounted on the front bumper, then this leads to a decrease in the air flow pressure under the car, which affects the quality of downforce while driving.

In addition, the spoiler in front of the car additionally pumps up air resistance due to its shape, but it is for this reason that air friction on the bottom of the car is reduced, which, in the end, again allows you to increase the quality of grip on the road. And one more additional property of the front spoiler is that it has a beneficial effect on the overall operation of the cooling system in the car.

How to choose the right spoiler for your car

Having decided to give his “swallow” additional aerodynamic characteristics and improve its appearance, the car owner decides to choose the perfect spoiler for himself.

The choice of product should be based both on the material capabilities of the motorist, and on those design features of the machine that will allow / will not allow the installation of one or another type of product. It should be noted that not every spoiler can be installed on a specific car model.

For example, almost any spoiler is suitable for sedans due to the specifics of their body - a shortened and tightened relief. The owners of such cars actively install lime spoilers of various shapes. For hatchback cars, it is recommended to install a duck tail spoiler - a kind of overlay on the rear window. A car in a station wagon is more inclined to install a spoiler on the roof or on the front bumper due to its large dimensions.

Standing out in an endless stream of cars in the city is not easy

How to make a spoiler for a car with your own hands

Wanting to save on buying a factory spoiler and installing it, some motorists are trying to make this element with their own hands. It should be noted that the independent manufacture of a spoiler is considered a rather difficult task, since the slightest flaws in its design can worsen the dynamic characteristics of the car. In addition, mistakes made when installing a homemade spoiler can directly affect the development of body corrosion.

However, if you are determined to make a spoiler for your car yourself, you can choose one of the most common options for making this element. In any case, you will need to prepare the necessary tools and auxiliary material in advance:

scissors;
metal scissors;
stationery knife;
hacksaw;
glue;
Sander;
sandpaper;
masking tape;
markers;
degreaser;
ground paint;
car enamel;

Creating a rear spoiler from galvanized iron and foam

The manufacture of a spoiler begins with its design. The first step is to decide on its shape and size. It will not work to do this “by eye”, since every millimeter of this product must be clearly calibrated:

The design of the spoiler should be determined with the help of an experienced car owner who already has experience in the manufacture of such products or through the involvement of an engineer.
The template is made on cardboard, to create it you will need to measure the width of the car and the luggage cover, mark the place of fasteners on the body.
After creating a template on cardboard, you need to cut it out.
Next, you need to circle a sheet of galvanized iron according to a template and cut out the spoiler frame with metal scissors. Traditionally, a galvanized sheet with a thickness of at least 1.5 mm is used.
After making the frame, you will need to increase the volume on it. One of the easiest ways to do this is to use styrofoam. Separate parts of the future spoiler are cut out from a piece of foam plastic with a clerical knife.
Each piece must be glued into place on the galvanized sheet.
After gluing, a gel coat (dust from aluminum) is applied to the foam layer, and a fiberglass cloth is applied on top of it. In this case, the fabric should lie in several layers, so that each new layer is denser and stronger than the previous one.
It is important that when applying fiberglass, there are no air bubbles between the layers.
After creating a durable coating, the entire surface of the spoiler should be coated with a polyester resin composition.
As soon as the product dries, it will need to be sanded with high quality.

It should be noted that primer, paint and varnish are applied only on a flat surface.

It is important to fit them well to each other, using both welding and glue. After degreasing, you can apply pieces of foam The frame is covered with foam

Making a fiberglass rear spoiler

Another affordable option for every motorist is to make a spoiler with your own hands from plastic materials.

Video: the process of creating a homemade fiberglass spoiler

The step by step process for making a fiberglass spoiler is shown below:

The shape of the future spoiler is first drawn on cardboard, after which the necessary fiberglass blank is cut out according to the template.
Racks and flaps are cut out of the same material.
These elements are fixed to the very base of the spoiler with an adhesive composition.
After creating the frame, you will need to glue it with fiberglass cloth.
When the reconstruction of a more dense structure is completed, it is recommended to impregnate the fiberglass with resin with the addition of aluminum powder to increase its strength.
After drying, the workpiece will need to be polished to create the perfect smoothness of the relief.
Next comes the painting work.

Fiberglass fabric is actively used in the manufacture of spoilers

We make a front spoiler from chipboard, polystyrene foam and polyurethane foam

Making a spoiler on the front bumper can not only give the car increased aerodynamic properties, but radically change the appearance of the car. However, the manufacturing technology of the front spoiler is somewhat different from the schemes for creating the rear one.

Video: how to make a tuning element yourself from improvised building materials

To make a spoiler from materials stored idle in your garage, it is enough to follow the algorithm below:

First you need to dismantle the front bumper from the car body. This will simplify all further operations.
Then it is necessary to glue the pieces of foam plastic to the chipboard blank with a reliable adhesive composition - both from the outside and from the inside.
Mounting foam will need to fill all the voids that will inevitably arise between the glued pieces of foam.
After the foam has dried, it will be necessary to give the spoiler the necessary shape with a clerical knife and special files.
Next, several layers of putty are applied, which are designed to give the element a finished appearance.
After the putty has dried, it will be necessary to sand the surface of the spoiler well in order to eliminate all types of irregularities.
At the final stage, a primer, enamel and varnish are applied.

After gluing with foam, mounting foam is applied

We make gypsum side skirts

Side spoilers or body kits are somewhat easier to make due to their relatively small size:

You will need to plaster over the place on the side of the body in which you plan to install the spoiler.
When applying plaster, it is necessary to leave a hole for air.
After the gypsum has hardened, it is necessary to grind the entire surface of the future spoiler and give it perfect smoothness.
It is recommended to blow out the gaps between the pieces of gypsum and along the edge of the spoiler with ordinary mounting foam.
After the foam has hardened, it is necessary to cut off its excess with a knife.
Then again follows the stage of careful grinding of the entire surface of the spoiler.
After the spoiler has been given perfect smoothness, you can start degreasing and painting it.

Thus, the spoiler can be made from a variety of materials - chipboard, galvanized iron, gypsum, foam, fiberglass, etc. It all depends on the experience of the motorist and his skills in working with certain materials and tools.

At the moment, spoilers on cars are considered a special chic, as they give the body a more toned and attractive look. However, when tuning your car on your own, you need to know when to stop, since installing spoilers on the roof, both bumpers and along the edges can turn the car into an unattractive vehicle that is completely devoid of aerodynamics. The operation of such a car will be unsafe, first of all, for the owner himself.
