The R1 Concepts drilled-and-slotted black brake rotor for 2004–2013 Mazda 3 rear right is a replacement rotor that updates that wheel position with a drilled-and-slotted braking surface and a black finish. Its open surface pattern is intended to help dissipate heat and channel debris and gases away from pad contact for more consistent braking feel, and it fits the specified Mazda 3 years and side as a direct replacement.
