Sold as either front or rear pairs. Available for standard or PCCB brakes.
Image is example only and may not be the exact rotor for your 991 GT3.
The rotor and hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by GiroDisc in the USA to their specifications. 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 grade 12 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
Converting to iron front rotors on PCCB equipped cars requires using pads designed for iron rotor equipped GT3's.
