Fits GT and Ecoboost with or without active exhaust. Does NOT fit the Dark Horse. Our 2024-Current Ford Mustang Rear Diffuser is a cover that fits over the center portion of the OEM rear valance, and is designed to provide extra rear end stability at high speed, as well as improved aesthetics. The Rear Diffuser is made with high-quality dry (pre-preg) carbon fiber finished in gloss or matte clear coat that is UV and scratch resistant. We are also offering Polyurethane versions in matte black finish. The Rear Diffuser is held on by factory bolts, as well as 3M™ Super Strength Molding Tape. The vehicle’s surface needs to be thoroughly cleaned with alcohol before the installation to ensure a proper bond with the 3M™ tape. We recommend applying adhesion promoter on the back side of the flares before installing the 3M™ tape to help with better adhesion. Optimal surface temperature for the 3M™ Super Strength Molding Tape is above 65°F (18°C). We highly recommend applying paint protection film on the carbon fiber products to prevent rock chip damage, and prolong the life of the finish.
