AC Schnitzer Carbon Fibre Rear Diffuser/Rear Lower Valance for BMW 1M E82 1 Series M Coupe - Carbon Fiber Bumper Insert, Twin/Dual Exit Exhaust Surround, Rear Undertray, Rear Bumper Trim - Genuine ACS BMW E82 1M Aero

Transform the back end of your BMW 1 Series M Coupe (E82) with a genuine AC Schnitzer rear lower valance manufactured in premium motorsport-grade composite. This sculpted aero insert delivers a race-bred look with a deep gloss finish, tight OEM-plus fitment and a purposeful twin-exit surround that complements the 1M’s wide-arch stance.

Built from authentic carbon weave and finished in a UV-stable high-gloss lacquer, this upgrade adds serious presence while resisting yellowing and weathering. Expect crisp edges, perfect alignment with the factory bumper, and a lightweight construction that replaces the plain plastic undertray. We have installed this upgrade for customers and the feedback has been outstanding, with flawless panel gaps and a sharper, more aggressive rear profile.
