Girodisc Ford Mustang S650 Dark Horse Brembo GT Rear Rotors
This is a 355mm direct replacement rotor for use with the 14" Brembo 4 Piston Brakes found on the 2024+ Dark Horse and GT Performance Pack with the Brembo Brake System.
These will provide a substantial weight savings over the Factory Iron Rotors on the Brembo equipped Mustang GT and Dark Horse.
This Girodisc rotor assembly is a direct replacement for the OE disc. No modifications are necessary. The assembly will bolt directly to your car and work with OE calipers and pads perfectly.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.
The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
