Ready to race, or just show off the performance capabilities of the
2018 Mustang? Add ROUSH Rear Valance Aero Foil Kit, designed to work
with the factory quad-tip GT valance!
utilizing techniques used in racing to improve aerodynamic
efficiencies, ROUSH Rear Valance Air Foils work to separate the airflow
beneath the car, allowing a smaller portion to follow the under-body
contours, adjusting rear downforce. Couple these foils with the ROUSH
Lower High-Flow Opening (P/N 422081)
and 3-Piece Chin Spoiler and Wheel Shroud Kit (P/N 422082)
for the complete lower aero package!
piece is made from high-strength TPO (thermal plastic olefin) with a
black stipple finish, for an OEM look and lasting durability. The
plastic is molded with high-pressure injection, the same process used
by OE automotive manufactures, which allows for impact resistance and
durable flexibility, while remaining lightweight with low density. Easy
installation means no trimming painting is required (drilling for
mounting is required). All required parts are included, such as
hardware, templates, and detailed instructions.
