The R1 Concepts drilled brake rotor for 1999–2003 Mazda Protege (front, left) is a black-finish replacement rotor with drilled holes to aid heat dissipation and maintain pad bite during repeated stops. It replaces the front left rotor on the specified Protege years to restore consistent braking feel and is suitable for routine service and brake refresh projects.
