D2-022 Girodisc Mercedes 330mm Rear Replacement Rings

Girodisc D2-022 Replacement Rotor Rings Only This kit is for two replacement 330mm rotor rings for the Girodisc A2-022 Two Piece Floating Rotors. It contains rotor rings and new installation hardware only, no aluminum center hats. Please note that unless specifically noted, Girodisc replacement rings are only designed to work with Girodisc hats. They are not designed to be used with other brands, including hats from cars equipped with 2-piece rotors from the factory. High Performance Replacement Brake Rotor Rings These rotor rings are attached to the rotor hat (not included) 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. Sold/priced per pair.
