Carbon Fiber Rear Diffuser with LED Brake Light

BMW G42 230i M Sport | BMW G42 M240i

Transform the rear-end appearance of your BMW G42 2 Series with this Carbon Fiber Rear Diffuser featuring an integrated LED brake light. Designed for M Sport and M Tech rear bumpers, this diffuser adds a wider, lower, and more aggressive motorsport-inspired appearance while maintaining a clean OEM+ finish.

Constructed from premium 2x2 twill carbon fiber, the diffuser provides lightweight strength, excellent durability, and a deep high-gloss appearance. A UV-resistant clear coat helps protect the carbon fiber against fading, yellowing, minor scratches, and everyday environmental exposure.

The integrated center LED brake light adds a distinctive performance-inspired lighting detail while improving the visual presence of the rear bumper. Designed around the factory dual-tip exhaust layout, this diffuser provides vehicle-specific fitment for compatible G42 models.
