The GiroDisc 380mm slotted front ring for 2015–2021 McLaren 540C and 570GT is a direct-fit replacement ring specified for setups that require spacers and exclude CCM. Built to match the factory diameter and mounting intent, it renews the slotted contact surface for service or upgrade use, helping channel pad residue away from the pad face and preserve consistent braking response under repeated use.
