Step-by-Step Installation Guide

Step 1: Front Splitter Installation

Clean the lower front bumper thoroughly.
Test-fit the splitter and ensure even alignment.
Secure using supplied screws into factory mounting points.
Tighten evenly — do not overtighten.

Pro Tip: Start from the centre and work outward for perfect symmetry.

Step 2: Side Skirt Extensions

Position the side skirts under the factory sill.
Use existing holes where possible.
Secure with self-tapping screws if required.
Check alignment from front to rear before final tightening.

Step 3: Rear Diffuser Installation

Remove the OEM rear diffuser using trim tools.
Align the gloss black diffuser starting from the centre.
Push firmly until all clips lock into place.
Secure with original fixings for extra strength.

Step 4: Rear Spoiler Fitment

Clean the boot lid surface completely.
Apply automotive-grade bonding tape or adhesive.
Align carefully before final placement.
Apply pressure for a secure bond.
