BMW G90/ G99 M5
Fitment: 2025-2026
Attention BMW G90/G99 M5 enthusiasts: experience the superior design and performance of AutoTecknic’s Dry Carbon Fiber Performante Rear Diffuser, crafted specifically for your M5. 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.
