Nissan AD (also known as Sunny B13/B14) is an iconic Japanese sedan of the 90s, which is still popular among tuning enthusiasts. The spoiler for this model not only transforms the appearance, but also improves aerodynamics, especially at high speeds. However, choosing the right part is not an easy task: the market offers hundreds of options, from budget plastic to premium carbon fiber products.

In this article we will look at all the nuances: from spoiler selection by year of manufacture (AD B13 1990–1993 vs B14 1994–1998) to step-by-step installation instructions with photos and videos. Let us dwell separately on common mistakes, which spoil the result, and we will give recommendations for painting to match the body color. If you are planning to upgrade your Nissan AD, here you will find answers to all questions - from price to compatibility with other tuning parts.

1. Why do you need a spoiler on Nissan AD: myths and real advantages

Many owners install a spoiler solely for aesthetics, but this part also has practical functions. The main task is reduction in lift on the rear axle, which is especially important for Nissan AD with motors GA16DE or SR20DEdeveloping high speeds. Without a spoiler, at speeds above 140 km/h the car may become less stable, especially during sharp maneuvers.

However, not all spoilers are created equal. For example, cheap "decorative" models made of ABS plastic often worsen aerodynamics, creating turbulence instead of downforce. To avoid this, choose parts with proven geometry - for example, original Nismo or replicas from APR Performance.

  • ✅ Installation advantages:
  • 🚗 Improved rear wheel grip at high speeds (relevant for track days).
  • 🎨 Visual lengthening of the body and sporty appearance.
  • 🔧 Possibility of integrating a brake light or rear view camera.
  • ⚠️ Cons:
  • 💨 Increased drag (can reduce top speed by 2–5 km/h).
  • 🔨 Risk of damage to the trunk if installed incorrectly.
  • 💰 High cost of high-quality carbon fiber models (from 20,000 ₽).
⚠️ Attention: Spoilers with a "wing" (type GT-Wing) are only effective at speeds above 160 km/h. For city driving they are useless and only add weight.

2. Types of spoilers for Nissan AD: which one to choose?

The market offers three main types of spoilers, differing in material, design and price. Let's consider each option taking into account its features Nissan AD B13/B14.

Spoiler type Material Price (₽) Pros Cons
Original (Nismo) CFRP/ABS 25 000–40 000 Perfect fit, light, durable High price, hard to find for B13
Universal ABS plastic 3 000–8 000 Cheap, wide range Requires modification of fastenings, fragile
Tuning (APR, Seibon) Carbon fiber/fiberglass 15 000–30 000 Lightweight, durable, improved aerodynamics Dear, it may not be suitable without registration

3. Step-by-step instructions for installing a spoiler on a Nissan AD

Installing a spoiler is a process that requires care and the right tools. Below are universal instructions suitable for most models. Opening hours: 2–4 hours (depending on the type of spoiler).

Required tools:

  • 🔨 Drill with a set of drills (∅3–5 mm).
  • 🔧 Set of screwdrivers (phillips, flat).
  • 🧴 Car sealant (for example, 3M Automotive Sealant).
  • 📏 Ruler and marker for marking.
  • 🔗 Fasteners: M6–M8 bolts, nuts, washers (usually included).

Clean the trunk of dirt and grease (use a degreaser)

Check the spoiler package (mounts, gaskets, instructions)

Remove the rear wiper (if it interferes)

Line the trunk with cardboard to avoid scratching the paint -->

Step 1. Marking and drilling.

Attach the spoiler to the trunk and mark the mounting locations with a marker. Make sure the part is located symmetrically relative to the center of the car. Drill holes in the trunk starting with a smaller diameter (eg 3mm), then widen to the desired size. Important: Don't drill too close to the edge of the trunk as this will weaken the metal.

Step 2. Installation of fasteners.

Insert the bolts into the spoiler holes and secure them with nuts from the bottom of the trunk. Pre-apply sealant to the contact areas to avoid corrosion. To be safe, use engraving washers — they will prevent the bolts from unscrewing themselves.

Step 3. Finishing.

After installation, check the gaps between the spoiler and the trunk - they should not exceed 1–2 mm. If necessary, adjust the position of the part by placing shims. If the spoiler needs painting, do it. before installation (see section 5).

What to do if the spoiler does not fit tightly?

If there are gaps left after installation, the reasons may be as follows:

1. Uneven trunk surface - treat it with putty before installation.

2. Spoiler deformation — warm the plastic with a hairdryer (60–80°C) and level it.

3. Incorrect fastenings - use adjustable brackets (for example, from Eibach).

⚠️ Attention: When drilling the trunk Nissan AD B13 Be careful - the rear light wires run under the trim. Before work, disconnect the battery and check the wiring diagram.

4. Painting the spoiler: technology and tips

If you bought a spoiler in its “raw” form (without painting), it must be coated with paintwork so that the part does not stand out against the background of the body. The painting process includes several stages, and the final result depends on the quality of each.

Materials for painting:

  • 🎨 Primer (for example, PPG DP40).
  • 🖌 Paint (selection by color code Nissan AD: KH3 for white, AH3 for red).
  • 🛡 Varnish (two-component, for example, Sikkens Autoclear).
  • 🧽 Sandpaper (P400, P800, P1200).
  • 🧴 Degreaser (App W99).

Step by step process:

  1. Sanding. Sand the spoiler P400to remove gloss and improve primer adhesion. For carbon fiber use P800 - it is more fragile.
  2. Primer. Apply 2-3 layers of primer with intermediate drying (15-20 minutes). For plastic parts, use primer with a plasticizer (for example, U-Pol Plastic Primer).
  3. Painting. Apply paint in 3-4 layers from a distance of 20-25 cm. Dry each layer for 10-15 minutes. For metallics, use a special gun with a nozzle of 1.3–1.4 mm.
  4. Varnishing. Coat the part with varnish in 2 layers. After drying (24 hours), polish with paste 3M Finesse-it.
💡

If the paint does not apply evenly, the cause may be too high a pressure in the spray gun (optimally 2.0–2.5 bar) or a dirty surface. Before painting, wipe the spoiler with a tack cloth to remove dust.

Tips for choosing colors:

Body color Nissan AD indicated by a code on a plate under the hood (for example, BH6 - dark blue metallic). If the original paint has faded, use spectrophotometer for precise shade selection. Popular colors for spoilers:

  • 🔴 AH3 - red (classic for SR20DE).
  • ⚫ KH3 - white (the most common).
  • 🔵 BH6 - metallic blue (suitable for B14 1996–1998).
  • ⚪ NN0 — black gloss (universal option).

5. Common installation mistakes and how to avoid them

Even experienced car owners make mistakes that spoil the result or lead to damage to the body. We have collected TOP-5 misses and ways to prevent them.

  1. Wrong choice of spoiler.

    Problem: The universal spoiler does not fit the width of the trunk Nissan AD, which is why you have to cut a part or trunk.

    Solution: Measure the width of the trunk in advance (at B13 — 1400 mm, y B14 - 1420 mm) and compare with the spoiler parameters.

  2. Ignoring sealant.

    Problem: Rust appears at the mounting points over time.

    Solution: Use anti-corrosion sealant (For example, Teroson MS 930) and process the edges of the holes.

  3. Re-tightening of bolts.

    Problem: The plastic spoiler is cracking and the metal of the trunk is deformed.

    Solution: Tighten the bolts to no more than 5 Nm (use a torque wrench).

💡

Before purchasing a spoiler, check its compatibility with your modification Nissan AD. For example, spoiler from B14 won't fit B13 without modifications due to the different shape of the trunk.

Other common mistakes:

  • 🔨 Using self-tapping screws instead of bolts - they rust and become loose.
  • 🎨 Painting the spoiler after installation - the paint will end up on the trunk.
  • 🚗 Neglect of balancing - the spoiler may vibrate at speed.

  1. Spoiler Nismo (carbon fiber).
  2. Diffuser APR.
  3. Body kits Nismo S-Tune (front bumper, skirts).
  4. Alloy wheels Enkei RPF1 (17x8).
  5. Spacers 15–20 mm to widen the track.
💡

When performing complex modifications, pay attention to the weight of the parts. A carbon fiber spoiler weighs ~1.5 kg, and a steel diffuser weighs up to 5 kg. Overloading the rear axle impairs handling.

FAQ: Frequently asked questions about spoilers on Nissan AD

❓ Is it possible to install a spoiler from Nissan Silvia S14 on AD?

Technically yes, but it will require significant modification: spoiler from Silvia 100–150 mm wider. You will have to cut the part or install it on spacers, which spoils the appearance. It is better to choose a spoiler specifically designed for AD.

❓ Which spoiler is better for daily driving: ABS or carbon fiber?

Suitable for urban use ABS plastic - it is cheaper and easier to install. Carbon fiber makes sense if you're doing track days or want to make your car as light as possible. However, keep in mind that carbon fiber is less resistant to impacts (for example, from gravel).

❓ Do I need to register a spoiler with the traffic police?

According to Order of the Ministry of Internal Affairs No. 399, spoiler refers to external lighting devices, only if it has built-in brake lights or lights. In this case, changes to the PTS are required. If the spoiler is purely decorative, registration is not required.

❓ How to remove the spoiler without damaging the trunk?

To remove the spoiler:

  1. Remove the decorative caps from the bolts (if any).
  2. Unscrew the bolts from the bottom of the trunk, holding the spoiler on top.
  3. Clean the holes from the sealant and treat WD-40if the bolts are rusty.
  4. When reinstalling, use new gaskets.
❓ Is it possible to paint the spoiler with a spray can?

Yes, but the result will be worse than with professional painting. If you decide to spray paint:

  • Use car acrylic paint (For example, Motip).
  • Apply thin layers from a distance of 20–25 cm.
  • After painting, coat with varnish in 2 layers.

Expect the can to give less even coverage, especially over large areas.
