This R1 Concepts rear rotor is a direct replacement drilled and slotted disc for the left side of the rear axle. The drilled holes and curved slots vent heat and brake gases away from the pad face for more consistent stopping power and cooler running temperatures, while the silver zinc coating helps resist corrosion. It is a bolt-on upgrade over a plain factory rotor.
