Girodisc A1-022DS Drilled/Slotted 360mm Front Brake Rotors Fits the Following Cars: C63 AMG non-S (2008-present) CLK63 AMG Black (2008) CLS55 AMG (2005-06) CLS63 AMG (2007-11) E55 AMG (2003-06) E63 AMG (2007-09) E63 AMG (2010-present) SL55 AMG (2003-06) SL63 AMG (2009-11) High Performance Drilled and Slotted Brake Rotors for Mercedes AMG This Girodisc floating iron rotor system is a direct replacement for your AMG front OEM rotors. No modifications to your car are necessary. The 360mm diameter rotors will bolt directly to your Mercedes AMG and work with the original calipers perfectly. The Girodisc front rotors are approximately 23.6 lbs vs. 34.5 lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When upgrading your original 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 drilled and slotted for incredible cooling, 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. A floating rotor will also self-center between the pads. Once your Girodisc system is in place, you can simply replace the cast iron discs as needed. Sold/priced per pair.
