The GiroDisc slotted front ring for 2008–2016 Audi S4 and S5 (B8) restores a slotted braking surface for the specified front rotor fitment. It is intended as a direct-fit replacement ring that preserves the slot pattern used to help clear pad deposits and aid heat and gas evacuation under heavy braking for the B8 S4/S5 front braking setup.
