The Girodisc system is a direct replacement iron rotor conversion from the OEM CCM 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 very common and also found on the Nissan GT-R, Cadillac CTS-V and most AMG Mercedes equipped with 6 piston calipers. If there is a specific pad compound you're after please contact us directly to provide the correct part numbers.
