The Specfab design promotes smooth airflow with minimal resistance keeping the brakes at the proper temperature.

Brake cooling is essential for S550 Mustangs that see track use. Not only is it necessary for safety but it improves performance and reduces expenses.

Increase Performance and Longevity

Supply a bunch air to your front rotors and keep them cool improving your braking performance and extending the life of your pads, rotors, brake fluid, and wheel bearings. The ducted backing plates supply air to the backside of the rotors where it is needed most allowing air to flow through the rotor veins lowering temperatures and maintaining braking consistency.
