The R1 Concepts drilled and slotted rear brake rotor is a direct-fit replacement for the left rear disc. The cross-drilled holes and curved slots vent heat and clear gas, water, and dust from the pad face so bite stays consistent through repeated stops. A silver zinc coating protects the non-braking surfaces from rust, and the one-piece cast iron disc bolts on in place of the factory rotor.
