The R1 Concepts drilled black brake rotor is a replacement rotor that restores the braking surface using a drilled pattern and black finish. It is specified for front-left fitment on 1994–2004 Ford Mustang models, giving an application-specific rotor option to replace a worn front disc while matching the vehicle's original disc location.
