PFC Brake Pads 0636.97.13.44 (97 Compound) A favorite since its debut, Performance Friction 97-Compound Racing Braking Pads continue to impress, winning numerous races in CART, ALMS, Grand Am, ASA, and Club Races everywhere. The 97-Compound has less initial bite and torque then the 01, while offering great modulation, a very flat torque curve, and excellent release characteristics. A naturally low-wearing pad, the 97 compound is popular in the endurance circuits and amongst Club Racers and Track-Day enthusiasts. PFC Brake Pads 0636.11.13.44 (11 Compound)  Based on the outgoing 01-compound, Performance Friction's 11-compound takes the same great high-bite and torque but with even better rotor and pad wear characteristics and improved bite, modulation, and release. Exhibiting a very high initial bite and torque, very little temperature induced torque rise follows. Less torque scatter exists for improved modulation with excellent release, helping to eliminate wheel lock at the end of a stop.     Fits Mazda Miata (94-05), Front

REPLACEMENT ROTOR RINGS ONLY. INCLUDES NEW INSTALLATION HARDWARE. DOES NOT INCLUDE ALUMINUM HATS. Discovery Parts 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. These Girodisc replacement rotor rings are direct replacements for the iron discs on your Girodisc two-piece rotors, and no modifications are necessary. New cap screws and washers are included with these replacement rotors. We do not recommend re-using the old hardware. The replacement rotor rings 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 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 rotor ring-only replacement to minimize replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

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

A1-249 Girodisc 2pc 380mm Front Brake Rotors for Nissan GT-R (CBA) FITMENT: Nissan GT-R (CBA) 2007-2011, Front w/ 380mm stock rotors is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline. 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 CMS RF-1 brake fluid (available from ), 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. Sold/priced per pair.
