R1 Concepts 623-40107R RNC Cross-Drilled Brake Rotor - Right

The R1 Concepts 623-40107R is a precision-engineered cross-drilled disc brake rotor from R1 Concepts' RNC series, designed as a direct-fit replacement for specific vehicle applications. Built to OEM specifications, this rotor installs without modifications and delivers a meaningful performance upgrade over stock brakes.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat buildup by up to 105°F, enhance ventilation, and prevent cracking under repeated thermal cycling
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 iron for excellent thermal stability, durability, and consistent stopping power
• Zinc Plated Finish: Full zinc coating applied to the hub and vane structure provides long-lasting corrosion protection and an aggressive appearance behind the wheel
• OE-Spec Direct Fit: Manufactured to original equipment specifications — no modifications or adapters required for installation
• Right-Side Rotor: This is the right (passenger side) rotor; sold individually
• Improved Heat Dissipation: Drilled pattern promotes airflow across the rotor face, reducing brake fade during repeated or hard stops

The R1 Concepts RNC drilled rotor is well-suited for daily driving, light towing, and street performance applications where improved thermal management and rotor longevity are priorities. Always replace brake pads when installing new rotors and follow the recommended bed-in procedure for optimal performance and even pad transfer.
