Type-GR Fiberglass Side Rocker Panel Splitter

The Anderson Composites Type-GR (GT350 Style) Fiberglass Side Rocker Panel splitter is engineered to improve the aerodynamic performance of your 2015-2023 Ford Mustang. These splitters feature a GT350-inspired design with deeper "planes" and "winglets" that effectively reduce lift by blocking airflow along the sides of the vehicle and preventing air from flowing underneath. By reducing aerodynamic lift, this splitter enhances vehicle stabilization, particularly during high-speed track driving, and contributes to improved overall traction. This results in exceptional stiffness and strength. Installation requires removing the original side rocker panels, mounting the new splitters onto the rocker panels, and then re-installing them as an assembly. A trim and panel tool kit is recommended for removing the OE rockers. The product does not include two replacement 1/4" x 1/2" rivets, and a drill and rivet tool are required. Additional clips and hardware may be necessary for optimal installation, and the lower mounting holes might need to be enlarged. The fiberglass material requires standard pre-paint preparation, including sanding and priming; any surface blemishes are typically removed during this process. Mounting tabs may also require minor adjustments for perfect fitment. This rocker panel splitter fits the 2015-2023 Ford Mustang models including Bullitt, EcoBoost, EcoBoost Premium, GT, GT Premium, V6, and Mach 1 variants. It is designed for 2-Door Coupe body styles.
