A1-072 Girodisc 2pc Front Brake Rotors FITS THE FOLLOWING CARS (Front Rotors): Mercedes CL55 AMG (2003-2006) Mercedes S55 AMG (2003-2006) is an authorized dealer for Girodisc products. As 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 disc. The two-piece floating disc 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. Girodisc two-piece floating rotors are lighter than OEM rotors. The resulting reduction in rotational and unsprung weight (approx. 11 lbs) allows for quicker acceleration and suspension response. When used with Girodisc Magic Pads on the street, Pagid or PFC racing pads on track, and RF-1 brake fluid (all available from ), 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 which is constructed in the USA and is 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 to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from braking while maintaining axial and radial float between the disc and the hat. These pins are secured by Grade-12 cap screws with hardened washers, mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise typically associated with floating rotors. The two-piece Girodisc design allows for disc-only replacement as well, minimizing future costs and delivering outstanding performance and brake cooling. Sold/priced per pair. Features: • Built for racing reliability and consistent performance • Compatible with demanding track environments • Designed for perfect fit and easy installation FAQs: Is this part track-proven? Yes, it has been tested extensively under racing conditions. Does it require professional installation? While not required, professional installation is recommended for best performance.

A2-017 Girodisc 2pc Rear Brake Rotors Girodisc Rotors to Replace the Front Rotors on the Following Cars: Mercedes C63 AMG (2008-11) High Performance Brake Rotors Replace The Stock C63 AMG Discs This Girodisc floating iron rotor system is a direct replacement for your Mercedes C63 AMG rear rotors. No modifications to your car are necessary. The Girodisc rotors will bolt directly to your C63 and work with the OEM calipers perfectly. By upgrading your C63 AMG brakes with lightweight high performance iron replacements, your factory bias is maintained as well as your ABS efficiency. The central hat section of the Girodisc rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's proprietary American-made cast iron and machined from start to finish in house at Girodisc. The disc utilizes a curved vane design, developed in racing to act as a centrifugal pump forcing cooling air through the disc. The disc and hat are joined by a floating mount system using 12 high-strength alloy steel drive pins manufactured by Girodisc in the USA and cadmium plated for long-lasting corrosion resistance. The drive pins bear the braking load while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side, allowing the rotor to grow with heat expansion while eliminating the rattle typically associated with floating rotors.

PFC 08 COMPOUND One of PFC's most popular compounds which came to fame in Endurance Sportscar and GT racing due to its performance in applications where smooth initial bite is a must. PFC 08 has a slight friction rise with temperature, excellent release and modulation characteristics. Despite its considerable performance, PFC 08 has the lowest wear rate of all PFC compounds and can easily match the wear characteristics of the other competitors' materials but with much higher bite and consistent performance across a broad temperature range.

A1-007 Girodisc 2pc Front Brake Rotors (Subaru STI 2004+) FITS: Subaru STI 2004+ (front) is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline. This Girodisc system upgrades the OEM brakes to a two-piece steel disc and aluminum hat. This two-piece floating rotor design will bolt directly to the Subaru STI front and work flawlessly with OEM calipers. Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response. Combined with Pagid or PFC performance brake pads and RF-1 brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc. The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors. This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs. Sold/priced per pair.
