To further enhance the styling and downforce of the rear end of the vehicle Vorsteiner designers have developed a lightweight carbon fiber aero diffuser which bolts onto the factory M3/M4 rear bumpers. Vorsteiner's Autoclaved Pre-Preg Carbon Fiber structure gives parts superior stiffness, aerospace strength & durability compared to traditional hand laid carbon fiber composites.
