The ROUSH Rear Valance Aero Foil Kit for 2018–2023 Mustang is designed to work with the factory quad‑tip GT valance and helps separate underbody airflow to adjust rear downforce for improved aerodynamic efficiency. Each foil is injection‑molded from high‑strength TPO with a black stipple finish for an OEM appearance and impact resistance. Lightweight and durable, the pieces were engineered with OEM CAD data for precise fit and lasting durability.
