The R1 Concepts drilled black brake rotor for 1990–1998 Audi 90 (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 model years, it matches the original rotor mounting pattern and dimensions so it fits correctly during routine brake service.
