GiroDisc Brake Rotors 2022+ Porsche 911 GT3/GT3RS (992)

Upgrade your factory Porsche GT3 brakes or replace worn out rotors with premium GiroDisc brake rotors.

The GiroDisc system is a direct replacement for the OE disc, no modifications are necessary. 

                            

The central hat section of the rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. Made from GiroDisc's proprietary cast iron poured in the USA and machined 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 alloy steel drive pins, manufactured by GiroDisc to their own specifications then cadmium plated for 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.

To keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side. This allows the rotors to grow with heat expansion and eliminates the rattle 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.
