Ford Brake Rotors

Girodisc Ford S550 Mustang Rear Rotors The Girodisc A2-067 Rear Rotors are a direct replacement for the factory rotors on the Ford S550 Mustang, engineered for performance enthusiasts who demand precision braking, reduced weight, and long-term serviceability. These 2-piece floating assemblies maintain the OEM fit and brake bias while providing measurable improvements in cooling and responsiveness. Lightweight Performance & Heat Management Each rotor features a 6061-T6 aluminum hat mated to a high-carbon cast iron rotor ring. This construction reduces unsprung and rotational mass, improving suspension response and acceleration. The 48 curved directional vanes act as a centrifugal pump, pulling cool air through the hub to dissipate heat and prevent fade during extended track sessions or spirited driving. Race-Ready Floating Design The Girodisc floating mount system connects the rotor ring to the aluminum hat via cadmium-plated steel drive pins secured with Belleville washers and spring clips. This setup allows the ring to expand under high heat without distortion, maintaining consistent pedal feel and preventing vibration or noise. The result is a rotor that performs flawlessly on both the street and track.
