Ford Mustang FR500S Front Rotors
The Girodisc 2-piece front rotor upgrade transforms the braking performance of your Ford Mustang FR500S. Designed as a direct-fit replacement for the factory rotors, these lightweight floating rotors bolt right up to your OEM calipers without modification. The result is reduced unsprung mass, sharper pedal feel, and vastly improved heat control—whether you're hammering laps or driving spiritedly on the street.
Each Girodisc rotor combines a 6061-T6 aluminum hat with a proprietary cast-iron ring, both engineered and machined in the USA. The internal curved vane design acts like a miniature air pump, forcing cooling air through the disc to stabilize temperatures and prevent fade during repeated heavy braking.
