The R1 Concepts drilled brake rotor for 1990–1997 Infiniti J30 (front left) is a black replacement rotor made for the front-left position on those model years. The drilled pattern aids venting compared with smooth rotors and gives a refreshed look while returning the braking system to service. It’s specified for direct replacement when the original rotor requires renewal.
