The R1 Concepts drilled black brake rotor is a replacement rear-left rotor for 1983–1990 Isuzu Impulse models. This drilled rotor in a black finish fits the rear left position and is intended as a swap to replace a worn rear rotor on the specified years, restoring the braking surface and providing a clear, vehicle-specific replacement option for that application and position.
