R1 Concepts 623-59022R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-59022R RNC Series brake rotor is a cross-drilled performance disc rotor engineered as a direct OE-style replacement with enhanced heat dissipation characteristics. Designed for the right/passenger side, this rotor delivers improved braking performance over standard smooth rotors while maintaining a clean, factory-compatible fitment.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote airflow across the rotor face, reducing heat buildup and minimizing brake fade during repeated or aggressive stops
• Zinc Dichromate Coating: Non-braking surfaces are coated with a silver zinc dichromate finish to resist corrosion and provide a clean appearance through wheel spokes
• Vented Construction: Internal vane structure maximizes thermal cooling between the rotor faces for consistent stopping performance
• Direct-Fit Replacement: Manufactured to OEM specifications for hassle-free installation with no modifications required
• Right Side (Passenger) Rotor: Sold as a single rotor for the right/passenger side position

R1 Concepts rotors are produced from high-carbon G3000 gray iron castings and undergo stringent quality control to ensure consistent thickness, runout tolerances, and balance. The RNC series is ideal for drivers seeking a cross-drilled upgrade over standard replacement rotors for everyday performance and improved rotor longevity.
