BMW M3 G80 Carbon Fiber Style A Rear Diffuser + Corner Extensions

Transform the rear styling of your BMW M3 G80 with the GSC TUNING Carbon Fiber Style A Rear Diffuser with Rear Bumper Corner Extensions.

Designed specifically around the aggressive proportions of the G80 M3 rear bumper, this Style A configuration combines a carbon fiber rear diffuser with extended left and right bumper corner sections for a more complete and integrated rear-end appearance.

The sculpted central diffuser section features pronounced vertical fins that add greater visual depth beneath the rear bumper, while the extended corner sections continue the carbon fiber styling toward both sides of the vehicle.

Compared with a standard center-only diffuser, the integrated corner design creates a wider visual profile and gives the G80 M3 a more cohesive motorsport-inspired rear end.

Manufactured from premium carbon fiber and finished with a high-gloss UV-resistant clear coat, the diffuser displays the distinctive carbon weave while complementing other carbon fiber exterior upgrades.

Pair it with GSC TUNING carbon fiber front lips, front canards, side skirts, mirror covers and rear spoilers for a complete G80 M3 carbon fiber exterior package.

Professional installation is strongly recommended.
