MHC+ Audi 8V RS3/A3/S3 Carbon Spoiler - Fitting Guide
Carbon Fiber Rear Spoiler
A flush, factory-look adhesive spoiler fit. Please read in full before fitting — warranty coverage does not extend to damage from incorrect installation.
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.
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.
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.

The contoured edge follows the natural curve of your boot lid for a flush fit.
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.
Apply Pressure Over 24 Hours
For the strongest bond, apply firm pressure across the spoiler every few hours while the adhesive fully cures.

Finished fitment — flush, low-profile, factory-look lip.
