The R1 Concepts drilled black brake rotor is a replacement rotor that restores the braking surface with drilled holes and a black finish. It is specified for front-left fitment on 1987–1988 Ford Thunderbird models, delivering a vehicle-specific rotor option to replace a worn front disc and maintain the original braking arrangement for those years.
