BMW M3 F80 / M4 F82 Carbon Fiber Rear Diffuser

Enhance the rear profile of your BMW M3 F80 or BMW M4 F82 with the GSC TUNING Carbon Fiber Rear Diffuser.

Designed to complement the factory performance styling of the F80 M3 and F82 M4, this rear diffuser integrates into the lower rear bumper and creates a more aggressive, motorsport-inspired appearance.

The sculpted design features defined vertical fins and large exhaust outlet sections, maintaining the signature quad-exhaust layout while adding visual depth to the rear of the vehicle.

Constructed from premium carbon fiber and finished with a high-gloss clear coat, the diffuser showcases the distinctive carbon weave while delivering a lightweight exterior styling upgrade.

For a complete carbon fiber package, pair it with GSC TUNING front lip, side skirts, rear spoiler, mirror covers and other carbon fiber exterior components.

Professional installation is recommended for optimum fitment and alignment.
