Owners Nissan Sunny FB15 Often faced with a dilemma: how to give the appearance of a practical sedan a more aggressive and sporty look without losing functionality. This is where a spoiler comes into play, which can radically change the perception of the car, adding dynamics to it even when static. This is not just a decorative element, but an important component that affects the air flow around the body at high speeds.
Choosing the right one aerodynamic body kit requires a careful approach to technical characteristics and driving style. Poor-quality tuning can not only ruin the appearance, but also create unnecessary resistance, increasing fuel consumption. In this article, we will look in detail at what types of spoilers exist for the FB15 model, what materials they are made from, and how to properly install them yourself to avoid mistakes.
Types of spoilers and their effect on the exterior
The tuning market offers many options for Nissan Sunny, ranging from laconic factory solutions to aggressive carbon wings. The most popular option for sedans in this class is the โfinโ or โdovetailโ, which is mounted on the trunk lid. This element visually shortens the rear of the car, making the silhouette more stocky and sporty. It is great for those who prefer moderate tuning while maintaining factory style.
A more radical solution is โGT-Wingโ or โduck tailโ spoilers, which protrude significantly above the surface of the trunk. They create active aerodynamic pressure, pressing the rear axle to the road, which is useful for aggressive driving. However, for urban use and the FB15 model, they often look unnecessarily bulky. It is important to consider the proportions of the body so as not to upset the balance of the visual mass of the car.
- ๐๏ธ Platform Spoiler: A classic option that imitates the factory style, often comes complete with a lip.
- ๐ฅ Sports wing: high stances, aggressive design, suitable for display at exhibitions.
- ๐ Diffuser with integrated spoiler: a comprehensive solution for the underbody and trunk.
The material used plays a decisive role in the durability and weight of the structure. Plastic options made from ABS plastic are the most affordable and lightweight. They are not subject to corrosion and are quite resistant to small stones flying from under the wheels. However, at low temperatures, such plastic can become brittle and crack from impact.
Fiberglass (fiberglass) offers the best balance between price and quality. It allows you to create complex shapes and is perfectly painted in any body color. Carbon spoilers are a premium segment, characterized by minimal weight and high strength, but their cost can be prohibitive for the mass consumer. The choice depends on your budget and tuning goals.
โ ๏ธ Attention: When installing an aggressive high-pillar spoiler, make sure that it does not block the view through the rear window when reversing, especially if you do not have a rear view camera.
Material selection and body compatibility
Before purchasing, you need to determine exactly which spoiler material is right for you. For Nissan Sunny FB15 The factory trunk geometry has specific bends, so universal parts often require adjustment. The plastic from which most budget models are made bends easily when heated, which makes it possible to adapt it to the curvature of the trunk lid, but this requires skill.
Fiberglass products are stiffer and require more thorough surface preparation. If you plan to paint the spoiler in body color, fiberglass will be the best choice, as it holds primer and paint well. Carbon is often sold ready-made with a varnish coating, which eliminates the possibility of repainting without losing the texture of the material.
| Material | Weight | Strength | Cost | Difficulty painting |
|---|---|---|---|---|
| ABS plastic | Low | Average | Low | Average |
| Fiberglass | Medium | High | Average | High |
| Carbon | Very low | Very high | High | Low (usually ready) |
| Metal | High | Maximum | Average | High |
Body compatibility Nissan Sunny FB15 - this is not only the shape, but also the attachment points. Some spoilers are attached with screws, which requires drilling holes in the trunk lid. Other options involve adhesive fastening with double-sided tape or sealant. Drilling is an irreversible process that can cause corrosion in the future if the edges of the holes are not treated with an anti-corrosion compound.
When choosing, be sure to check the availability of components: bolts, nuts, rubber seals and instructions. Chinese manufacturers often skimp on the kit, and you will have to buy additional fasteners separately. The quality of the metal in the kit is also important: cheap bolts can rust and stick, making dismantling difficult in the future.

Preparation for installation and necessary tools
Installing a spoiler is a process that requires care and preparation. Even the highest quality spoiler can be damaged if installed incorrectly. Start by thoroughly washing the trunk and degreasing the surface where the part will be attached. Use special degreasers or alcohol to remove traces of wax, bitumen and dirt.
You will need a set of tools: a screwdriver or screwdrivers, a drill (if you choose the bolt-on option), metal drills, a marker, a ruler and a level. If you plan to glue the spoiler, be sure to buy high-quality automotive double-sided tape (for example, 3M) and polyurethane sealant for waterproofing.
- ๐ ๏ธ Set of screwdrivers and bits: for tightening fasteners with the required force.
- ๐ Measuring instruments: tape measure and level for perfect alignment.
- ๐งช Chemistry: degreaser, antistatic, plastic cleaner.
Marking is a critical step. Before drilling or gluing, position the spoiler against the trunk and center it. Use masking tape to secure the piece in position and stand back a couple of meters to assess symmetry. Any error at this stage will be noticeable immediately after installation.
โ๏ธ Preparing to install the spoiler
Step-by-step installation instructions
The installation process depends on the type of fastening chosen. If you choose the bolt-on version, open the trunk lid from the inside. Remove the plastic covering if it covers the mounting points. Use a marker and ruler to mark the holes for drilling, making sure they line up with the spoiler seats.
Drill the holes carefully using a drill of the appropriate diameter. Immediately treat the edges of the holes with an anti-corrosion compound or paint to prevent the metal from rusting. Apply a layer of sealant to the mounting points to prevent moisture from getting inside the trunk, which can lead to corrosion or mold.
When installing with glue, the process is even simpler, but requires precision. Apply a bead of sealant or apply strips of double-sided tape to the back of the spoiler. Remove the protective film and carefully press the part to the trunk, following the pre-made markings. Make sure the spoiler is level and does not move.

During this period, do not wash the car or expose the part to stress. For reliability, you can additionally secure the spoiler with bolts from inside the trunk, if the design allows it.
โ ๏ธ Attention: Never screw the spoiler to the thin steel of the trunk lid without reinforcement with washers. This can cause the metal to deform and cracks to appear around the holes when vibrating.
What should I do if the spoiler doesn't line up with the holes?
If the seats do not match, do not try to force the bolts. This will lead to distortion and deformation. It is better to use universal glue and sealant, or modify the spoiler with a file, if the material allows.
Aesthetics and aerodynamic efficiency
Many owners install spoilers purely for appearance, but it is important to understand the real effect of aerodynamics. For sedan Nissan Sunny FB15 with a low-power engine, the standard platform spoiler will not have a significant effect on downforce at speeds up to 120 km/h. Its main task is to break up the air flow, reducing turbulence behind the trunk.
This can slightly improve the car's stability on the highway and reduce wind noise, which is often caused by the shape of the rear window. However, if you install a spoiler that is too large and high without adjusting the suspension accordingly, you can get the opposite effect: the car will start to โbounceโ at speed due to excess lifting force.
- ๐ฌ๏ธ Reduced turbulence: reducing air turbulence behind the trunk.
- ๐ Flow stabilization: improved flow around the rear of the body.
- ๐จ Visual balance: harmonization of the car silhouette.
It is also important to consider the color and finish of the spoiler. If the part is not painted in body color, it will look like a foreign body. High-quality painting with varnish transition and use of original paint codes Nissan will make the part indistinguishable from the factory one. Carbon fiber (carbon fiber) will add a premium look, but requires careful care of the varnish.
Before painting the spoiler, be sure to cover the mounting holes with masking tape to prevent paint from getting inside, which will make it difficult to install the bolts.
Care and maintenance of the aerodynamic element
The spoiler, like any other body element, requires regular maintenance. When washing your car, pay special attention to the attachment points and joints with the body. Use soft sponges and special body shampoos to avoid scratching the varnish or spoiler coating. Avoid contact of abrasives with plastic elements.
Check the condition of the fastenings every six months. Vibration from the road can loosen bolts or cause the spoiler to come loose if it's attached with glue. If you notice any play or cracks in the sealant, correct the problem immediately to avoid tearing the part off as you go. This may be dangerous for other road users.
In winter, be careful when clearing snow and ice from the spoiler. Do not use sharp ice picks or metal scrapers, as they can easily damage the paintwork and the material itself. Use soft brushes and warm water to defrost. If the spoiler is made of plastic, it may become brittle in the cold, so avoid impacts.
Regularly checking the condition of the fasteners and sealant will extend the life of the spoiler and ensure driving safety at high speeds.
Frequently Asked Questions
Do I need to drill holes to install a spoiler on Nissan Sunny FB15?
It depends on the chosen model. Some spoilers are attached solely with double-sided tape and sealant without drilling. Others require bolt-on installation, which necessarily involves drilling holes in the trunk lid. Always check the contents before purchasing.
