BMW M240i G42 Carbon Fiber Rear Diffuser

Transform the rear profile of your BMW M240i G42 with the GSC TUNING Carbon Fiber Rear Diffuser.

Designed specifically for the G42 platform, this rear diffuser features a sculpted multi-fin layout that adds depth and aggression to the lower rear bumper while maintaining a clean OEM+ appearance.

Constructed from premium carbon fiber, the diffuser combines lightweight construction with a high-gloss clear-coated finish that highlights the distinctive carbon weave. Its vehicle-specific shape follows the factory bumper contours for a more integrated appearance.

The central vertical fins create a motorsport-inspired rear profile, making this diffuser an ideal upgrade for owners looking to enhance the visual presence of their M240i.

For a complete exterior carbon fiber package, it can be paired with GSC TUNING carbon fiber side skirts, rear bumper side trim panels, spoiler, mirror covers and other exterior components.

Professional installation is recommended for optimum alignment and fitment.
