1

Remove Your Existing Spoiler

If a spoiler is already fitted, soften the old adhesive with a heat gun — keep it moving at all times to avoid damaging the paint underneath. Use a heat gun at your own risk.

2

Clean the Mounting Surface

Wipe the boot lid with a glue and tar remover until fully free of old adhesive, grime, or wax. Leftover residue weakens the bond.

3

Dry Fit Before Committing

With the backing tape still on, rest the spoiler on the boot lid to confirm alignment — the contoured ends are shaped to wrap the lid's curve.

Spoiler contour detail

The contoured edge follows the natural curve of your boot lid for a flush fit.

4

Peel, Position, and Press

Once confident in placement, peel the backing tape and move the spoiler into final position. Press firmly along its full length to seat the adhesive.

5

Apply Pressure Over 24 Hours

For the strongest bond, apply firm pressure across the spoiler every few hours while the adhesive fully cures.

Maintenance
Stick to shampoo and light wax or polish. Acidic cleaning products can react with the finish and cause lasting damage — avoid these on or near the carbon fiber surface.
