Show original supplier description

The Street Aero Classic Edition Rear Diffuser is engineered to enhance the aesthetic of the 2018-2023 Ford Mustang GT. Crafted from a robust 6mm thick Aluminum Composite Material (ACM), this component boasts superior UV resistance, weatherability, and an anti-corrosion skin that ensures a lasting, brilliant look. While the product page primarily showcases fitment for the 2018 Ford Mustang GT, broader compatibility is noted for RWD models within the 2018-2023 range, including those with the Performance Package or California Special trims. Installation is straightforward, with documentation suggesting the use of basic tools such as a 1/4 socket and an Allen key, or a drill, screwdriver, and 1/4” and 10mm wrenches, depending on the specific part. Professional installation is recommended for all Street Aero aerodynamic components. This diffuser is proudly designed, produced, and shipped from California, USA.
