Girodisc D2-078 Alfa Romeo 4C Rear Replacement Ring FAQs
Are these compatible with the OEM Alfa Romeo 4C brake setup? No. These are designed only for Girodisc two-piece rotor hats and will not fit factory one-piece rotors.
Will these work with upgraded street or track pads? Yes. They’re compatible with all major pad brands including Ferodo, Pagid, and Hawk for both street and track driving.
Do these require any modifications for installation? None. They bolt directly to your existing Girodisc aluminum hats using the included floating hardware.
