/ 01 · OVERVIEW

Enhance the rear end of your G82 and G83 M4 with OEM style prepreg carbon fiber rear diffuser extensions. These rear extensions are constructed using 100 percent genuine prepreg carbon fiber, delivering improved strength, reduced weight, and a more consistent fit and finish compared to traditional wet carbon fiber.

The controlled manufacturing process ensures uniform weave quality and a refined surface appearance that integrates cleanly with factory styling. This set includes a two piece rear extension kit and is compatible with both OEM and M Performance style rear diffusers.

Please note this is an aftermarket product and is not affiliated with or produced by BMW.
