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 in combination with Alpha's new G87 M2 carbon rear diffuser, the carbon rear underbody floor kit is also meant to work as a package with the CSL trunk lid and designed to both increase downforce and reduce drag. While taking its cues from the G87 M2's existing bodylines, the rear diffuser and underbody floor kit enhance the rear styling to maximum aggression. The pre-preg carbon construction in a 2x2 weave minimizes weight while maximizing strength.

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
