Competition Motorsport is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most Girodisc products the same or next business day to ensure we meet your delivery deadline. Fits Nissan GT-R (R35, 2007+)  The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. These Girodisc rear rotors are approx 18.8 lbs. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. The central hat section of the Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved-vane design, developed in racing to act as a centrifugal pump forcing cool air through the disc. The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads. Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats. Sold/priced per pair
