Genuine BMW M Performance Carbon Flow-Through Rear Spoiler - G80 M3 | G82 M4

The BMW M Performance Carbon Flow-Through Rear Spoiler for the G80 M3 and G82 M4 generates rear downforce through a twin-channel design rather than a conventional solid wing or trunk lip. Air accelerates through a center gap in the carbon structure, producing measurable downforce at higher speeds without the aerodynamic drag penalty of a full rear wing. BMW engineered this spoiler specifically for the G80 M3 and G82 M4 to support track use while maintaining the production roofline silhouette.

This is a Genuine BMW M Performance part made from pre-preg dry carbon fiber, autoclave-cured to the same quality standard used across BMW's motorsport program. It bolts directly to the G80 M3 and G82 M4 trunk lid at the OEM mounting points — no drilling, no modification, no permanent alteration. Unlike aftermarket flow-through spoilers, this is engineered to the factory mounting geometry of the G80 and G82, with the gloss carbon weave matched to the full M Performance exterior package. Non-returnable.
