DESCRIPTION
Upgrade the braking performance of your Porsche 911 GT2 RS Clubsport 991.2 with Girodisc 2-piece Brake Rotors A2-250.
The Girodisc system is a direct replacement for the original disc; no modifications are necessary.
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 proprietary cast iron, poured in the USA and machined in-house from start to finish 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 10 high-strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and 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 prevent noise when cold, the pins are mounted with anti-noise spring washers on the rotor side, allowing the rotor to expand with heat while eliminating 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.
