The R1 Concepts drilled-and-slotted black brake rotor for 2000–2005 Chevrolet Astra (rear left) is a replacement rotor with drilled-and-slotted machining intended to assist heat release and pad cleaning on the rear-left wheel. Finished in black for a cohesive look, the overview sticks to the explicit Mexico rear-left application from the source and refrains from extrapolating fitment beyond that listing.
