• Zinc Plated Finish: Silver zinc coating provides corrosion and rust protection, extending rotor life and maintaining a clean appearance behind the wheel
• OEM Dimensions: Engineered to OEM specifications for a direct bolt-on installation with no modification required
• Left-Side Application: Specifically designed for the driver-side (left) position — confirm fitment using your vehicle application guide
• Balanced and Tested: Each rotor is precision balanced and tested to minimize vibration and pedal pulsation

The R1 Concepts RNC series offers an affordable upgrade path for drivers looking to improve braking feel and rotor longevity over standard OEM replacement rotors. Compatible with OEM and aftermarket brake pads.
