D2-147 Girodisc Rear Replacement Rotor Rings

REPLACEMENT ROTOR DISCS ONLY. INCLUDES NEW MOUNTING HARDWARE. DOES NOT INCLUDE ALUMINUM HAT. Discovery Parts 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 replacement rotor system is a direct rotor disc replacement for the Girodisc two-piece hat and rotor and no modifications are necessary. 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 our 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 only replacement to minimize replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.
