Enhance the side profile of your BMW with the MHC+ GTX Side Skirts for the F80 M3 and F82/F83 M4, a premium carbon fibre upgrade designed to visually lower the vehicle and create a clean, uninterrupted aerodynamic profile. Developed as a core component of the MHC+ GTX aero system, these side skirts connect the aggressive styling of the front splitter and rear diffuser, delivering a more cohesive and purposeful appearance across the entire vehicle.
Manufactured from 100% pre-preg (“dry”) carbon fibre, the GTX side skirts combine lightweight construction, exceptional rigidity and a flawless OEM-style finish. Their clean, refined design avoids unnecessary styling excess, allowing the factory body lines and premium carbon weave to take centre stage.
