The GiroDisc slotted front ring for 2017+ Audi RS4 and RS5 (B9) is a direct-fit ring that uses slots to help evacuate gases and debris from the pad interface for steadier pad contact. Intended for B9 RS4 and RS5 front brake assemblies, the ring mounts to the appropriate center hat and is supplied as a front-ring replacement matching Audi RS4/RS5 braking configurations.
