Brake Rotors

Girodisc D2-220 Replacement Rotor Rings (380mm) Girodisc replacement rotor rings are direct replacements for the iron discs on your Girodisc A2-220 380mm two-piece rotors, with no modifications necessary. New cap screws and washers are included with these replacement rotors. We do not recommend re-using the old hardware. (This kit is contains two cast-iron discs and associated hardware. No aluminum center hat.) The replacement rotor rings 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 and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from braking 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. Rotor ring-only replacement helps to minimize costs and deliver outstanding performance. Sold/priced per pair.

Girodisc two-piece, fully floating rotor assemblies help shed unsprung weight and rotating mass from the front axle of the Toyota Corolla GR, while being far more durable in track use.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at the Girodisc facility in Bellingham, WA, from domestically-sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodized finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware. We also recommend replacing them if a crack leads to the edge of the ring. Sold and priced per pair. If you would like help choosing front brake pads, give us a call at (844) 438-7244.
