Installing an aftermarket spoiler is one of the most popular modifications for improving your car’s aerodynamics, aesthetics, and even handling performance. However, fitting a spoiler correctly requires careful preparation and the right tools to ensure a secure and professional finish. Here’s a step-by-step guide to fitting an aftermarket spoiler to your car, including everything you need to know for a smooth installation.
Preparation Is Key
Before diving into the installation, proper preparation ensures a seamless fit and prevents damage to your car’s paintwork or structure.
Things to Consider:
- Choose the Right Spoiler: Ensure the spoiler is designed for your car’s make and model or is a universal spoiler that fits correctly.
- Inspect for Damage: Check the spoiler and your car’s surface for any scratches, dents, or imperfections that could affect installation.
- Location: Install the spoiler in a clean, well-lit, and dry environment, such as a garage or workshop.
Tools You’ll Need
- Drill with appropriate drill bits (often 6mm or 8mm for most spoiler kits)
- Tape measure and masking tape
- Torque wrench and screwdriver
- Silicone adhesive/sealant (if applicable)
- Touch-up paint or rust inhibitor (if needed)
- Cleaning supplies (isopropyl alcohol, microfiber cloth)
- Template or installation guide (usually provided with the spoiler)
Preparing the Surface
Step 1: Clean the Area
Use a car-safe cleaner or isopropyl alcohol to thoroughly clean the area where the spoiler will be mounted. This removes dirt, grease, or wax that could interfere with adhesion or drilling.
Step 2: Mark the Position
- Place the spoiler on the trunk or designated mounting surface to check alignment.
- Use masking tape to outline the spoiler’s position, ensuring symmetry on both sides.
- Double-check measurements with a tape measure to confirm even placement.
Types of Spoiler Installations
There are two main types of spoiler installations: bolt-on and adhesive-mounted. Here’s how to handle each.
A. Bolt-On Spoilers
Bolt-on spoilers require drilling holes into the car’s surface for secure attachment.
Step 1: Use a Template
Most spoilers come with a paper or plastic template. Align it with your masking tape markings, and use it to mark the exact drill points.
Step 2: Drill the Holes
- Use a drill bit that matches the bolt size included with the spoiler kit.
- Drill slowly to avoid damaging the paint or distorting the hole.
- Apply touch-up paint or rust inhibitor around the holes to prevent corrosion.
Step 3: Mount the Spoiler
- Secure the spoiler using the provided bolts and washers.
- Use a torque wrench to tighten bolts evenly, avoiding over-tightening that could crack the spoiler or damage your car’s surface.
B. Adhesive-Mounted Spoilers
Adhesive-mounted spoilers are easier to install but require a strong bond for long-term durability.
Step 1: Apply Adhesive
- Use the adhesive tape or silicone sealant provided with the spoiler kit.
- Carefully apply the adhesive along the spoiler’s mounting surface, ensuring even coverage.
Step 2: Position and Secure
- Align the spoiler with the masking tape markings and press it firmly into place.
- Use masking tape or clamps to hold the spoiler in position while the adhesive cures. Follow the manufacturer’s curing time, which is typically 24-48 hours.
Finishing Touches
Step 1: Clean Up
- Remove any remaining masking tape or marks with isopropyl alcohol.
- Wipe down the spoiler and surrounding area for a polished look.
Step 2: Test Stability
- Check the spoiler’s stability by gently applying pressure on all sides.
- If it wobbles or moves, tighten bolts or reapply adhesive as needed.
Tips for a Professional Installation
- Read the Instructions: Always follow the manufacturer’s installation guide for specific details.
- Have a Friend Help: A second pair of hands can help with alignment and stability during installation.
- Use High-Quality Adhesive: Cheap adhesives may fail in extreme temperatures or over time.
- Consider Professional Installation: If drilling or alignment seems daunting, a professional shop can ensure a flawless fit.
Final Thoughts
Fitting an aftermarket spoiler is a rewarding modification that adds both style and function to your car. By following the proper preparation steps, using the right tools, and choosing the appropriate installation method, you can achieve a secure and professional-looking finish.
Take your time, double-check your work, and enjoy the upgraded look and performance your spoiler brings to your vehicle!
