External tuning of a car is a kind of uniform, clothing by which both the car and its owner, naturally, are greeted. What details relate to external tuning? All kinds of body kits, trims, chrome parts, anti-wings (aka spoilers). All cars, without exception, even before production, pass through the hands and eyes of designers who create this or that appearance for them, but it often happens that the happy buyer and owner of the car remains dissatisfied with this design, and then... Then there is a need for improvement and external improvement your car, the search begins possible solutions. One of these decisions becomes a strong desire to buy a spoiler. However, it is not at all necessary to buy it. If you read the following general information about how to do DIY spoiler, then it is quite possible that your obsession with buying a store copy will disappear.

Material and Tooling Options

There are several well-known ways to make a spoiler. Moreover, some craftsmen use tin blanks as a basis for the form, others use plaster castings, others cut them out of wood or foam plastic, and some, especially daring ones, can create a tuning masterpiece even from an ordinary newspaper. We will not take a specific example and dwell on it, because this is a matter of taste, skill, the size of your car and personal capabilities, but in any case you will need the following set of tools and materials:

• quite a large piece of fiberglass;
• reflective tape;
• two or three cans of paint;
• about the same number of cans of primer;
• approximately 3 kg of epoxy glue;
• five pieces of brushes for applying paint and glue;
• two rolls of sandpaper (coarse for shaping and fine for sanding).

By the way, get ready to work hard and painstakingly, because there is no way to complete such work in a day or two. Overall, expect to spend at least two weeks if you want a nice, neat spoiler.

Nuances of each material

1. When working with iron, be careful and attentive to the edges of the cut pattern, because metal can seriously damage not only clothing, but also your own hands.
2. When using foam plastic as a template, consider its hardness and density. To process it, either ordinary sandpaper, a file or even a sharp stationery knife can be used.
3. The good thing about plaster molds is that, when poured, they take on almost any shape you have in mind. But do not forget that gypsum is a heavy and very fragile material. With one wrong move, it can not only split, but also turn into dust. In addition, you will still have to make some kind of form into which to pour it. It is better to use the same foam or wood.
4. Well, the most masterpiece way is the newspaper method. To make a base for a spoiler from such an unusual material, you don’t need much intelligence. It is enough to unroll the sheet, roll it very tightly into a tight tube, securing it at the edges with glue so that it does not unwind, and then repeat these operations several times, laying newspaper tubes one after another, depending on the size of the designed spoiler.

In principle, this is far from full list all kinds of materials suitable for use and production of a spoiler. If the theory is clear to you, then the base can be made from anything - even from bread crumb, like criminals in prisons.

Final process

After making the base, you must do what is called "reinforcement". Simply put, taking a ready-made base, you need to give it the specific desired shape and wrap it in several (three or four) layers of fiberglass. Then the entire structure must be impregnated with epoxy glue, allowed to dry and harden, and a primer applied. After applying and drying the primer, the product is carefully (exactly carefully!!!) sanded with sandpaper so that the aerodynamics are ideal, and then it is painted and dried again. Finally, a reflective tape is glued to the aft part of the finished spoiler, although this is not necessary, and the spoiler is installed on the trunk lid, for example. Now your car will take on a sporty and fast look, and you will be greeted by the clothes... that you made yourself.

And just for fun:

", many motorists, having installed something more like a football goal on their "basin", classify their "masterpieces" as pumped-up cars.

But if you don’t like this scenario and you decide to approach this issue thoroughly, I recommend this article to you as a guide with which you can create the right wing with your own hands, spending a minimum of money and your free time.

The purpose of the wing is to press down on the rear drive part, thereby increasing traction and improving.

My article today is about how to make a rear spoiler with your own hands , without resorting to the help of specialists, using available tools and the necessary material for this.

The creation of the spoiler took place directly on the model; a rigid frame of the spoiler was designed, after which the part was sculpted and glued using a rough matrix (template). It takes about ten days to do everything, provided that your hands are straight and there is plenty of time. The design was spotted on one of the models, to be honest I don’t even know which one I saw something similar on, but as often happens, the hands simply reproduce some scraps or fragments from memory, and as a result something of their own comes out.. .

So, let's go...

DIY spoiler: template

First of all, I estimated the approximate width of the wing , after which I cut off the required piece of hardboard. The convexity of the roof was reproduced using a patterned chipboard guide.

Then I cut out a strip in the shape of an arc and screwed it to the bottom of a strip of hardboard, after which, due to the load, the hardboard itself formed the outer surface of the future spoiler.

Plasticine helped to fix the wing in space. Using tape, I sealed all the places where the plasticine slides will be placed. Using thick layers, I formed the spoiler support struts, then installed a wing strip made of chipboard on them. By the way, plasticine perfectly allows you to adjust the angle of inclination of the spoiler plane, as well as its symmetry.

The next stage is cutting out brackets from hardboard, which are installed on the sides of the wing close to the car body pillars. It remains to fix them with plasticine from the inside. The final stage of creating a template matrix was gluing the hardboard with fiberglass scraps; it took several hours for the resin to polymerize (dry), after which my frame was ready.

Removal of the frame was successful - there were no deformations or distortions, the spoiler model was removed easily. Thus, I succeeded top part a future template according to which it will be possible to sculpt the matrix and wing.

The spoiler matrix that I created is divided into two parts. The whole beauty of making a spoiler “quickly” is that the first step is to create the upper part of the model, remove the matrix from it and only then add the bottom.

To form the spoiler matrix you need to: use thin and thick glass mat. A layer of fiberglass mat is placed on top of the wool fiberglass mat to secure and strengthen the matrix.

The second stage of making a spoiler with your own hands is adjusting the spoiler layout.

After the resin has hardened, the inverted wing can be turned over and checked what happened inside. Next, I built symmetry and formed the side posts (supports).

Then I corrected the corners of the model - I patched them up and cleaned them together with the matrix flange.

I sealed the lower part of the spoiler with fiberglass and made holes for the bolts; they should be located as close as possible to the spoiler model, this will allow the matrix halves to fit better and more tightly.

I trimmed the “hairy” edges of the matrix using a grinder, since the thickness of the plastic consisting of 2 halves is approximately 6-7 mm thick. Once trimming is finished, you need to clean up the edges a little, this will save you from unpleasant glass splinters.

Opening the resulting spoiler matrix turned out to be extremely inconvenient; I had to first use a knife blade. He held it between the half-forms with slight opening movements. After that, I inserted wedges and all sorts of wood chips into the thin gap that had formed. After some time, after not entirely pleasant manipulations, the half-forms of the matrix are still revealed.

To clean the matrix from the remaining plasticine, I used plastic scrapers, after which I thoroughly blew everything with a hot industrial hairdryer and removed the residue with a sponge.

The part is formed with the obligatory use of gelcoat; it is not recommended to use an external protective layer on the spoiler at all. The fact is that after painting there is a possibility that the texture of the fiberglass will begin to appear. Also be sure to apply the release coat of matrix and gelcoat using a wide brush.

I would like to note that aluminum powder gelcoat is not without its drawbacks, the main one of which is the polyester resin base for molding. Paraffin, which is part of this resin, can rise to the surface of the gel during polymerization... When everything hardens, the gelcoat has to be lightly sanded.

While the gelcoat is drying, there is time to cut the glass mat and dilute a thick “gruel” consisting of aerosil and “polyester”; this substance will be needed to fill the sharp corners of the matrix.

You can understand what contact molding is by looking at the example of my spoiler. The gelcoat is coated with polyester resin, then covered with glass mat. I make the first layer from the three hundredth layer. Then resin is applied to the surface of the glass mat, after which it is nailed to the gelcoat using a brush. To get rid of air bubbles, which are extremely undesirable, use a special roller with a transverse notch or make your own.

I recommend trimming the edges of the freshly formed part using a sharp knife until the polyester resin has changed from a jelly-like state to a solid one. This is important because this seemingly insignificant detail can save a lot of time. The resulting spoiler halves must be removed from the matrix and the edges slightly modified with sandpaper.

Climax...

DIY spoiler- ready! In addition, in the process I managed to create a matrix according to which I will be able to make more than one of these in the future if necessary. The process of gluing the two halves occurs as follows: on the edges of the spoiler halves, which are installed in the matrix halves, strips of slurry consisting of aerosil and polyester resin are laid out in a small heap. When you put the two halves together, these strips of porridge come into contact, firmly gluing the two parts into one.

Now you can get the finished wing and proceed to the final stage: sanding the hardened mess and preparing the spoiler surface for painting.

Well, something like this... From now on you know how to make a spoiler with your own hands, moreover, now you can create matrices and templates yourself with subsequent casting of a wing of any shape. By the way, having once figured out how to make a matrix with your own hands, in the future you can use this experience not only for spoilers, but also for the manufacture of body parts, such as aerodynamic body kits, skirts, air intakes and much more.

Before you get to work, it’s worth finding out what types of spoilers there are and what their purpose is. This will help you decide on the manufacturing method and speed up the results.

Tuning or functionality?

When people talk about tuning a car, a spoiler or a wing is most often thought of. The wing is an additional part of the car, which, thanks to the gap, increases downforce at high speeds, above 80 km/h. This ensures greater vehicle stability and traction on the road surface. Calling it a spoiler is not entirely correct, but most car enthusiasts know it by this name.

A spoiler or, more precisely, a lip spoiler is a part for a different purpose and does not need a gap for this. Its task is to reduce air turbulence and reduce the aerodynamic drag coefficient. It is usually mounted on the trunk lid, especially if there is a sharp transition from a horizontal to a vertical surface.

The wing and spoilers can be installed on the car initially during production or during operation by the car owner himself. Those installed and made independently usually have a decorative function and do not fulfill their intended purpose. If the rear wing is installed incorrectly or incompletely, the car also loses technical specifications, and in this case the spoiler has a negative effect on the car.

Wing - a mandatory element sports cars when driving on race tracks. The cars are equipped with an adjustable rear wing, which is automatically activated when the pilot presses the gas pedal. This detail significantly increases speed on straight sections and helps when overtaking.

Wing - a mandatory element of sports cars

In order for the wing to cope with the task, it is installed not only on the rear of the car, but also on the hood and on the sides, the so-called body kit and sill extension, respectively. Otherwise, at high speed, as a result of the operation of the rear spoiler, the car will rise above the road front. The body kit in the car also serves as an additional cooler for the internal parts of the car, thanks to the redirection of the air stream.

The disadvantages of the wing include:

• decrease ground clearance auto;
• poor visibility in the rear window;
• considerable cost if you buy ready-made and high-quality ones.

If you are going to buy a spoiler, pay attention to the material and manufacturer. A quality product will not be cheap. A professional technician should install such a part; it is better not to do it yourself.

The material for making the wing can be:

• fiberglass is the most popular;
• ABS plastic - light, flexible, becomes brittle over time;

New style spoiler made of ABS plastic

• silicone with organosilicon polymers;
• carbon - excellent characteristics, but high price.

Spoilers can also be custom - these are designer single copies - and factory ones, which are produced in large quantities. The wing can be attached to the car body with double-sided tape or self-tapping screws if the structure has racks. Depending on the design, steel or aluminum is used for the racks.

We create a spoiler ourselves

Many motorists make their own trunk spoiler. This significantly saves money and in some cases looks no worse than expensive tuning parts.

Before you start making a wing yourself, you should purchase materials and tools for the job. You will need:

• foam for the base, thickness 5 mm;
• spray paint to match the car;
• metal sheet, thickness up to 1.5 mm;
• epoxy adhesive;
• carbon fiber.

You will also need brushes, sanding paper and other small items.

Spray paint

The work of creating a wing with your own hands begins with cutting out the base from foam plastic. Racks are made according to your preferences from sheet metal. The foam piece should then be glued to the posts and layers of carbon fiber or fiberglass should begin to be glued onto the foam using epoxy glue. Before gluing a new layer, let the previous one dry.

After the workpiece has dried, the future spoiler is primed and minor irregularities are smoothed out with putty. Then you should sand the workpiece with fine-grained sandpaper, removing subtle roughness.

We paint the spoiler and, after complete drying, install it in the intended place of the car.

There is another way to make a spoiler with your own hands. The manufacturing technology is similar to the previous one. But the base is not polystyrene foam, but gypsum. To do this, cut out the shape you like from polystyrene foam, line it with film and fill it with plaster. There should be two such parts, they are glued together and begin to be covered with fiberglass. Next, the process is the same as in the previous method. This option, how to make a spoiler yourself, is more labor-intensive, but also quite simple and affordable.

Making a spoiler for a car with your own hands

There is also a way on the Internet self-made based on polyurethane foam. You can spend a lot of effort on it, but the result is amazing. The base is formed from polyurethane foam on a car previously wrapped in film. Then they cut out the desired shape and polish it. Then they also use epoxy resin and fiberglass, but the top layer is putty mixed with fiberglass and only then regular putty. The further process is similar to the others: priming, sanding, painting, polishing. But as a result, the visor made on rear window with your own hands it comes out indistinguishable from the factory one and looks like a native part of the car.

When making it, you should remember that it doesn’t matter how to make a spoiler for a VAZ or a foreign car, the main thing is that the result is worthy of attention and brings aesthetic pleasure to the owner.

On motorcycles they also install a part related to the spoiler - a fairing. Performs a protective function: the motorcyclist from headwinds and dashboard in case of an accident. Thanks to various, sometimes completely unique designs, the bike stands out from the crowd.

And here are ways on how to make a motorcycle fairing yourself. According to the manufacturing principle, they do not differ from those given above. The only difference is in the shape of the fairing and its layout.

Polyurethane foam spoiler

Some car owners, before starting work on creating a spoiler with their own hands, draw patterns on available materials - plywood, hardboard. They make it easier to adjust sizes on a machine. You can also find ready-made drawings of various modifications of the wing on the Internet.

Whatever your decision regarding the choice of wing, spoiler and fairing, always be guided primarily by what functions you expect from them. Installation of part for improvement only appearance without taking into account its capabilities can lead to unexpected results on the track.

Buy a factory spoiler or make it yourself - the decision is made by the car owner, based on his capabilities. But it’s worth studying various photo and video materials on the Internet, manufacturers’ offers and other nuances. If you are not sure about own strength, remember that sometimes it’s easier to buy than to spend time making it yourself.

Spoilers from a car store are not always suitable for your car. It happens that a few centimeters are missing. You can, of course, cut a brand new spoiler, making an insert of the required length, but you can make a spoiler yourself, reducing its cost by almost half! A nice bonus is that you can shape the spoiler to your own taste. We stock up on time and get to work.

When choosing between polyurethane foam sealant and polystyrene foam, we are inclined to favor the latter, due to its obviously low comparative cost. We will need a sheet of polystyrene foam, 5 cm thick and 1 x 1 m in size. We cut the wing blade diagonally, otherwise the width of the sheet simply will not be enough. Next we make a stand for the number.

As you know, Japanese numbers are smaller than Russian ones and more square, which is why our numbers don’t look right in the places allocated for them. We cut out the blank and take epoxy glue in a paper box. Instead of fiberglass, old silk fabrics from unnecessary things are suitable. It will take you a couple of days to glue the stand, and sanding and painting will also take a few days. In this case, it is better to take the paint in cans and cover it with varnish on top.

The result is this:

Then... not a spoiler - the lip. It's easier to do. We remove and turn over the bumper, glue the foam blank. It was weakly held on the bumper with the help of silicone auto sealant. We remove it and give it shape. Then we wrap it in polyethylene bags. You can use women's tights. We simply stretch them in two layers onto the mold and coat them with epoxy glue. Once they are completely dry, remove the blank from the lip.

And in order to avoid problems with this, bags are exactly what is needed, since epoxy does not stick to them. Only after a few days or even a week does it completely polymerize, although it seems to have dried out within a day. However, a lot here depends on the hardener, or more precisely, on its quantity: the more of it, the faster the epoxy polymerizes, but at the same time it becomes more fragile. It’s also good to add a payer for flexibility.

Even after this, the glued lip does not have the required strength, so we glue two more layers of silk fabric and a reinforcing mesh from the inside for strength. But instead of silk, it is better to use fiberglass or carbon fiber so that the lip does not crumble! Even the reinforcement mesh doesn't help! Then we start sanding, after which we apply a primer, and start painting.

Let's get to the spoiler. We make fastenings by cutting out plates from 1.5 mm sheet steel, drilling holes in increments of 2-3 cm, 3 mm wide, and welding two 6 mm nuts at the base. After that, we glue them into the foam blanks we have.

Then we cover the wing blade with two layers of fabric and assemble it. Apply the glue with a brush, then wash it in a solvent or under running water hot water. You should not prepare a lot of glue at once, more than 200 ml, it is difficult to use it all in one go.

To prevent foam chips from sticking to you, touch the faucet often - this will help relieve static. It is best to glue up to 3 layers of fiberglass at intervals to allow the resin to polymerize. This process accelerates several times at temperatures up to 120 C.

We glue the spoiler, putty and paint it with three cans of black paint.

You can make a piece of glass for the stop bar from plexiglass or plexiglass, but in this case, it is made of epoxy.

New spoiler installed. Let's summarize the materials spent:

1. polystyrene foam - one sheet;

2. fiberglass about 2 m;

3. fastening and welding;

4. LEDs 12 mm – 2 pcs.;

5. neon lighting in the spoiler;

6. two cans of paint;

7. 3 cans of primer;

8. epoxy glue about 2 kg;

9. wires – 2 meters;

10. Chinese brushes - 3 pieces;

11. sandpaper.

And all this work took 2 months. If you are enthusiastic enough, get started! But it’s still better to paint it in a salon.

Installing a spoiler on the trunk is the dream of every second motorist. This product fits any car model, making its exterior more sporty and dynamic. Many people know it as a “wing”, and it looks like a goal in football.

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

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

The spoiler improves stability and handling, especially when cornering

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

DIY spoiler for VAZ

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.

First, 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 will 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:

• polystyrene foam 1m x 1m with a thickness of 50 mm;
• auto enamel to match the color of the car;
• sheet of steel with a thickness of no 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 Gazelle Next is the same for any car and involves the following work:

• Using polystyrene foam, cut out the future sharp part of the spoiler according to the prepared pattern. Do this diagonally to ensure the size of the product matches the required size.
• Make fasteners for the tuning element. To do this, cut plates from a steel sheet and 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 secure the plates. As a base under the visor, install nuts with a diameter of 6 mm. Glue the nuts to the foam blanks and cover them with fiberglass, applying it in 2-3 layers. After gluing each layer, wait until the composition dries, and then apply the next one for successful polymerization of the glue. For the same reason, do not prepare a lot of glue at once - mix it as you apply it. To wash off the composition, hot water is enough. To prevent the build-up of static voltage that is common with fine foam chips when cutting, keep contact with grounded surfaces while working.

Spoiler for Gazelle Next

• If the rear spoiler will have a brake light or other optics, lay the wiring inside in advance and install the backlight.
• Apply primer and putty to the surface to level it. Sand the piece using fine-grit sandpaper to prepare for painting.
• Apply auto enamel from a can to the workpiece or use a brush.
• The next stage of how to make a spoiler for a VAZ is applying varnish to the workpiece. Before varnishing, treat the surface with a degreaser.

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