The Girodisc system is a direct replacement for the OE disc however a different brake pad with an annulus (pad swept area) of 66mm or less must be used.  This is done to keep the rotor weight at a reasonable level.  If we manufactured a rotor with the same annulus as the OEM CCM rotors they would be unnecessarily heavy.  The necessary pad shape is FMSI 1405 which we can provide in several compounds.

Girodisc 2 piece rotor ring replacements come complete with all new hardware and full instructions for re-assembly. Girodisc rotors are made from proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. ​

All Girodisc purchased from FrozenRotors.com are cryogenically treated for maximum brake rotor life.
