The R1 Concepts E-Line drilled and slotted brake rotor is a direct-fit replacement disc for the front left corner. It is cast from G3000 grade iron and silver-zinc plated to resist rust and corrosion, while cross-drilled holes and diamond-pattern slots vent heat and sweep gas, dust, and water off the pad face for more consistent bite under repeated stops. Each rotor is double-disc ground and mill balanced for smooth, quiet, vibration-free braking.
