R1 Concepts 623-47036L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47036L is a drilled disc brake rotor from the RNC Series, engineered to deliver reliable stopping performance with enhanced heat management. Manufactured to OEM specifications using G3000 grade cast iron, this rotor installs as a direct-fit replacement with no modifications required.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to prevent cracking while improving ventilation and heat dissipation
• G3000 Cast Iron Construction: Provides the durability, stability, and braking consistency expected from an OEM-grade rotor
• Zinc Plating: Corrosion-resistant zinc coating applied to the hub and vane structure to extend rotor lifespan and maintain appearance
• OEM Direct Fit: Manufactured to original equipment specifications for a straightforward, bolt-on installation
• Left/Driver-Side Application: Designed specifically for the driver-side (left) position — confirm fitment before ordering
• Improved Heat Dissipation: Drilled pattern promotes airflow across the rotor face to reduce brake fade during demanding stops

The R1 Concepts RNC Series drilled rotor is a strong choice for drivers seeking a performance-oriented upgrade over standard OEM rotors. As with all new rotor installations, a proper bed-in break-in procedure is recommended to achieve optimal braking performance and longevity.
