Ford S550 Mustang Front Rotors
Take the already impressive stopping power of your Mustang GT, Bullitt, or Mach 1 to the next level with Girodisc two-piece floating front rotors. Designed specifically for the 380mm Brembo-equipped S550 platform, these rotors deliver the heat management and performance edge needed for street, autocross, and track-day driving—without altering OEM fitment or balance.
Performance You Can Feel
The Girodisc system is a direct bolt-on replacement that works perfectly with factory six-piston Brembo calipers. Each rotor weighs in at approximately 24.1 lbs, shedding nearly 10 lbs per corner compared to the stock setup. This reduction in rotational mass improves steering response, suspension behavior, and overall braking consistency under hard use.
