Add aggressive styling and extra visibility to your G80 M3 or G82 M4 with this pre-preg carbon fiber LED rear center diffuser.
Transform the rear-end of your 2021+ BMW G80 M3 or G82 M4 with the Carbon Fiber LED Rear Center Diffuser — a bold styling and functional lighting upgrade that integrates seamlessly into the aggressive G8X design language.
This rear center diffuser is crafted from 100% pre-preg dry carbon fiber with a 2x2 weave, finished in a high-gloss clear coat that resists UV fading and maintains its premium finish over time. The built-in center LED light can be custom-wired as either a brake light or an always-on rear fog/rain light, enhancing both visibility and style.
Installation is straightforward — requiring only two wire taps to the existing taillight harness. US-spec models, where brake and turn signals activate simultaneously, may benefit from optional coding to separate those functions for advanced customization.
