The Girodisc system is a direct replacement for the OEM rear cast iron rotors on the Porsche 992 GT3 & GT3RS and the 718 GT4RS. No modifications are necessary, allowing use of unmodified factory pad shapes unlike most aftermarket solutions for these Porsches. The Girodisc rotors will bolt directly to your car and work with perfectly with the excellent OEM Brembo calipers. By upgrading your brakes with lightweight, high performance replacements (as opposed to a big brake kit), both the factory brake bias and ABS actuation dialed-in by Porsche engineers are preserved.
Girodisc two-piece floating rotors are lighter than the OEM Porsche rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response.
When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid , you have an amazing solution to overheating, cracking and warping rotors.
The central hat section of each Girodisc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.
The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by class 12.9 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.
The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.
