Optional Rear Spoiler Extension

🧰 Tools You’ll Need for the Installation

Before starting, prepare the following:

Torx Screwdriver Set
Ratchet and Socket Wrench
Plastic Trim Remover (to avoid scratches)

Clean Microfibre Cloths

⚙️ Step-by-Step Installation Guide

Step 1 – Front Splitter Installation

Clean the front bumper surface thoroughly.
Align each splitter piece and mark the screw points.
Mount using provided screws — don’t overtighten.
Double-check symmetry before fully securing.

💡 Pro Tip: Adding a thin rubber seal between splitter and bumper enhances the OEM look and minimizes vibration.

Step 2 – Side Skirt Extensions

Position the side skirts directly under factory rocker panels.
Use existing holes if possible; otherwise, use self-tapping screws.
Ensure even alignment along the car’s length.

Step 3 – Rear Diffuser

Remove the stock diffuser using a trim tool.
Test-fit the new gloss-black diffuser — start from the center.
Push until you hear all clips click into place.
Reinstall screws or clips for extra support.

💡 Optional: Install the rear spoiler or exhaust tips for a complete look.
