GIRODISC A1-066 Front Brake Rotor Kit for PORSCHE 911 (991) Turbo/Turbo S/(981)Cayman GT4

The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc 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. 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.

When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.

If your car same with OEM center lock wheels please select the center lock drive pin option.
