BMW G80/G82, M3/M4 Carbon Fiber Body Kit Rear Bumper Side Splitter V.2

Enhance the rear-end styling of your BMW G80/G82 M3 & M4 with these Carbon Fibre Rear Bumper Side Splitter V.2 Aero Extensions — designed to add sharper lines, increased aggression, and a more motorsport-inspired appearance to the rear profile of your vehicle.

The V.2 design features a more sculpted and aggressive aero profile compared to standard rear side splitters, giving the rear bumper a wider, lower, and more track-focused look while perfectly complementing the bold factory styling of the G80/G82 platform.

Manufactured from premium high-quality carbon fibre, these aero splitters provide lightweight durability and a flawless gloss carbon weave finish that elevates the overall appearance of the vehicle. Their precision-contoured design integrates seamlessly into the factory rear bumper for an OEM+ fit and finish.

Whether paired with a rear diffuser, front lip, side skirts, or spoiler, these V.2 rear aero extensions complete the aggressive styling package for any street or track-inspired build.
