The R1 Concepts drilled-and-slotted black brake rotor for 2006–2007 Mazda 6 rear left is a replacement rotor that supplies a drilled-and-slotted braking surface and black finish for that wheel location. The rotor's open surface pattern is intended to aid heat dissipation and channel debris and gases away from pad contact for steadier braking, and it fits the Mazda 6 years and side listed as a direct replacement.
