Description

The Anderson Composites rear diffuser is meticulously crafted from premium 3K, 2x2 twill carbon fiber cloth using a vacuum-infused process. This component is finished with a marine-grade gel coat, enhanced with UV inhibitors and polished to a high luster, ensuring both durability and aesthetic appeal. The construction process focuses on achieving an exceptional carbon-to-resin ratio for high product stiffness and strength. It is intended to complement other aerodynamic enhancements like splitters and spoilers for a balanced performance package. This rear diffuser is specifically designed to fit the 2013-2014 Ford Mustang GT500, 2013-2014 Mustang GT with the App Package, and the 2013 BOSS 302 models. Professional installation is recommended, as the rear bumper must be removed for proper mounting. Furthermore, the mounting tabs may require modifications, and minor adjustments might be necessary during the installation process, underscoring the recommendation for expert fitting. The product includes a California Proposition 65 warning regarding exposure to chemicals like Styrene and Bisphenol A.
