The GiroDisc 350mm slotted front ring for Porsche 911 Carrera S and 4S (996/997) is a direct-fit replacement ring sized to match factory front rotor dimensions. Intended for service replacement or rotor refreshes, the slotted contact surface assists in moving pad residue out of the contact zone and helps maintain consistent pad bite and braking response during routine and more spirited driving.
