• Zinc Plating Coating: Full zinc plated finish protects against corrosion, extending rotor life and maintaining a clean appearance behind the wheel
• Double Disc Ground Braking Surface: Promotes faster, more even brake pad bed-in for quieter and smoother stops from the first drive
• OEM Direct Fit: Built to original equipment specifications — no modifications, adapters, or special tools required for installation
• Left / Driver-Side Fitment: Sold individually as the driver-side rotor; verify fitment against your specific vehicle application

The R1 Concepts RNC Series drilled rotor is an excellent choice for drivers seeking enhanced braking performance, improved heat management, and a sportier appearance without compromising ride comfort or daily drivability.
