The M Performance rear diffuser Carbon underlines the sporty appearance of the M3 and M4. In the diffuser, three succinctly shaped ridges are incorporated, which enhance the sporty appearance. A TÜV registration is not necessary. All parts are already homologated with the complete vehicle. All parts of the M Performance aerodynamic components are coordinated and perfectly adapted to the vehicle design. The production of the rear diffuser carbon of the M Performance aerodynamic catches takes place in elaborate manual work and gives the components a high-quality appearance.
