Description

The Vorsteiner BMW F8X M3/M4 GTS Carbon Fiber Aero Rear Diffuser is engineered to maximize aerodynamic performance on your F80 BMW M3 or F82 M4. Its meticulous craftsmanship ensures precise fitment, allowing it to seamlessly integrate with the vehicle's contours for optimized visual appeal and aerodynamic function. Constructed from resin pre-impregnated, vacuum-formed carbon fiber material, this diffuser is 20%-30% stiffer and stronger than those made with wet-layup methods. It utilizes a combination of unidirectional, 1x1, and 2x2 carbon weaves to minimize weight while maximizing strength and rigidity. The material is further protected by a 4-stage UV inhibiting clear coat for added durability and a glossy finish. This vehicle-specific design is intended to match the factory BMW M body lines and contours. It is compatible with the 2015-2018 BMW M3 (F80) and the 2015-2020 BMW M4 (F82), specifically models equipped with the S55 3.0L Twin Turbo Engine.
