R1 Concepts 623-72017R RNC Series Cross-Drilled Brake Rotor - Right

The R1 Concepts 623-72017R is a right-side RNC Series cross-drilled brake rotor engineered to deliver improved thermal performance over a standard OEM replacement rotor. Precision-drilled holes across the rotor face vent heat and gases away from the braking surface, helping to reduce brake fade during demanding driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to maximize heat dissipation while minimizing the risk of cracking under stress
• G3000 Cast Iron Construction: Manufactured from G3000-grade cast iron for excellent structural integrity, consistent bite, and long service life
• Zinc Plated Finish: A zinc plating applied to the hat, hub, and vane areas provides corrosion resistance and helps maintain appearance over time — the coating on the braking surface wears away normally during break-in
• Double Disc Ground: Both faces are precision ground to OEM thickness tolerances, promoting faster, more even brake pad bed-in and quieter operation
• Direct OEM Replacement Fit: Manufactured to original equipment specifications with no modifications required for installation
• Right-Side Fitment: Designed specifically as a right (passenger side) rotor — always replace in axle pairs for balanced braking performance

R1 Concepts recommends following a proper break-in procedure after installation to fully seat new brake pads to the rotor surface. Always replace brake pads when installing new rotors for optimal performance and safety.
