MHC BMW M3/M4 OEM Style Side Skirts In Pre Preg Carbon Fibre are stunning additions, giving your car a more sporty and premium look. These side skirt options are very similar to our MHC performance-style side skirt, however they lose the aggressive fin design for a more sleek and OEM look. The addition of the OEM style side skirts enhances the road presence, and the OEM-style carbon weave complements any carbon extras fitted to your car from the factory.
