The R1 Concepts drilled black left-front brake rotor for 2016–2020 Ford Mustang applications is a direct replacement rotor with a drilled face and black finish. It fits the left-front position for those Mustang years and preserves factory wheel clearance and mounting. For balanced braking, replace the opposite-side rotor at the same time to maintain even rotor performance.
