The R1 Concepts drilled brake rotor for 1989–1991 Mazda RX-7 (rear, right) is a black-finish replacement rotor with a drilled surface to aid heat dissipation and preserve pad bite during repeated stops. It serves as a vehicle-specific replacement to restore consistent braking feel at the right rear wheel, suitable for routine service and brake refresh projects.
