The Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake rotors. These two-piece floating rotors will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight, high-performance replacements (as opposed to a big brake kit), your factory brake bias is maintained, along with your ABS efficiency.
Girodisc two-piece floating rotors are lighter than OEM brake 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 Competition Motorsport RF-1 brake fluid (available from Competition Motorsport), you have an amazing solution to overheating, cracking and warping rotors.
The central hat section of the disc 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 Grade-12 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.
