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 F430 or 360, front or rear, 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 Competition Motorsport 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.

Girodisc A1-022DS Girodisc 2pc Front Brake Rotors (Drilled & Slotted) $1,400.00
Drilled and Slotted 360mm Two-Piece Floating Front Brake Rotors Girodisc Rotors to Replace the Front Rotors on 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.
