The R1 Concepts drilled black brake rotor is a replacement rotor that restores the braking surface with a drilled pattern and black finish. It is specified for rear-left fitment on 1993–1998 Mercury Cougar applications, offering an application-focused rotor option for replacing a worn rear disc on those model years while maintaining correct fitment.
