Dramatic exits come standard with this carbon fiber upgrade. The multi-piece Dinan rear diffuser spotlights the rear of the car and creates a new "floor" that visually appears to make the vehicle lower and more aggressive. Despite the diffuser encompassing the exhaust exits, great care was taken to ensure enough room was supplied to accommodate even large tipped exhausts, like Dinan's own. Additionally, the diffuser adds wrap arounds to each of the rear quarters that allows a harmonious and uniform visual continuation with the Dinan front lip and side skirts for a perfectly matched cosmetic solution. Features: 2x2 gloss twill carbon fiber manufactured to be impact resistant, durable and strong Clear coated for maximum UV protection and fade resistance Includes 3M double sided tape and mounting screws for easy installation with a clean fit and finish

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.

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.

2x2 weave; carbon pre-preg construction

Rather than replace the full diffuser and have potential fitment challenges with various exhaust options Dinan has opted to retain the factory gloss black lower portion of the diffuser and only replace the upper diffuser surround with a carbon fiber accent piece. This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace. Features: 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact-resistant, durable, and strong Clear-coated for maximum UV protection and fade resistance Utilizes factory mounting tabs for an easy installation with a clean fit and finish Pair together with the Dinan Rear Side Splitters to complete the full rear look
