These Girodisc replacement rotor rings for the Nissan R35 GT-R are Girodisc's updated variant. If you're not sure these are correct for your Girodisc rotors, please contact us.

They the are direct replacements for the iron discs on your Girodisc two-piece rotors, and no modifications are necessary. New cap screws and washers are included with these replacement rotors. We do not recommend re-using the old hardware.

These rings will not work with factory center hats. They are designed to work with Girodisc hats only.

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 to their 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 ring-only replacement to minimize replacement costs and deliver outstanding performance and cooling.

Sold/priced per pair.
