The GiroDisc slotted front ring for 2005–2013 BMW 335i (E9X), including xDrive models, is a direct-fit replacement ring for the front brakes. It restores a slotted braking surface to replace worn rings and help channel pad deposits away from the contact zone, supporting steadier pad engagement and consistent braking feel during everyday and more demanding driving conditions.
