The GiroDisc slotted front ring for 2015–2020 Alfa Romeo 4C is a direct-fit replacement ring for the model's front brakes. Intended as a service or upgrade part, the slotted surface renews the rotor contact face to help channel pad deposits away from the pad area and preserve steady pad engagement, supporting predictable braking feel under varied driving conditions.
