The R1 Concepts drilled black brake rotor for 1984–1987 Audi 4000 Quattro (front left) is a direct-fit replacement that restores the vehicle's braking surface with a drilled face and black finish. Specified for the front left position on those Quattro years, it matches the original rotor mounting pattern and dimensions so it fits correctly during routine brake service.
