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 discs. The two-piece floating rotors will bolt directly to the car and work with OEM calipers perfectly.
By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Girodisc rotors are lighter than OEM pieces. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
When used with Pagid or PFC racing brake pads and Competition Motorsport RF1 racing brake fluid, you have an unbeatable 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 and 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 8-10 high strength alloy steel drive pins manufactured by Girodisc in the USA and are cadmium plated for corrosion resistance. The alloy drive pins transfer braking loads while maintaining axial and radial float between the disc rotor and hat to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The pins are secured by Grade12 cap screws with hardened washers and mounted with anti-noise spring washers .
The two-piece Girodisc design allows for rotor-ring only replacement to minimize future replacement costs and deliver outstanding performance and cooling.
