The R1 Concepts drilled-and-slotted black brake rotor for 2006–2015 Mazda MX-5 Miata front left is a replacement rotor that updates that wheel position with a drilled-and-slotted braking surface and 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 MX-5 Miata years and side as a direct replacement.
