This advanced rear diffuser engineered with our autoclave vacuum-forming technology mounts seamlessly onto the factory location elevating both the aerodynamic efficiency and visual appeal of your M5. Constructed from authentic 3K Twill-Weave (2X2) Pre-Preg Carbon Fiber the diffuser is finished with multiple layers of high-gloss UV-resistant clear coat providing exceptional durability and an unmistakable sleek aesthetic.

Our dry carbon fiber manufacturing process embodies motorsport-grade quality designed for lightweight strength and precise fitment. Through meticulous autoclave vacuum forming each carbon fiber strand is resin-impregnated molded and cured under vacuum resulting in an even lighter and stronger structure than conventional “wet” carbon fiber. This process minimizes imperfections and ensures a flawless finish free of pinholes or air pockets. The AutoTecknic Performante Rear Diffuser includes robust mounting clips for a secure fit and for optimal installation we recommend removing the rear bumper to facilitate clip insertion. Redefine your BMW G90/G99 M5 with the unparalleled style weight savings and performance benefits of this premium diffuser.
