The R1 Concepts drilled-and-slotted black brake rotor for 2000–2005 Chevrolet Astra (rear right) is a replacement rotor machined with drilled holes and slots to help manage heat and pad surface during braking at the rear-right position. With a black finish for visual uniformity, this description adheres to the explicit Mexico rear-right application in the source and avoids broader compatibility claims.
