Alpha-N's V2 carbon rear diffuser for the G90 M5 or G99 M5 Touring is significantly more aggressive and functional vs the more OE-styled V1 piece. Featuring an integrated "underbody floor" section around the center of the diffuser, the V2 carbon piece both increases downforce and reduces drag vs the V1 variant.

All Alpha-N exterior parts are focused on functional aerodynamic improvements, and the G9X M5 V2 rear diffuser is no exception while also enhancing the rear styling.

Product Details:

2x2 weave; carbon pre-preg construction

Alpha-N has a reputation for pushing the boundaries of performance and style. With Alpha-N's connection to BMW Motorsport and their track record of producing high-quality carbon parts, their latest G8X M2 / M3 / M4 components are no exception. Designed as a 2 part system, but available to be installed on its own, Alpha's new carbon rear diffuser takes its cues from the G87 M2's existing bodylines and enhances the rear styling, striking the perfect balance of aggression and elegance. The pre-preg carbon construction in a 2x2 weave minimizes weight while maximizing strength.
