R1 Concepts 623-56015R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-56015R is a RNC Series cross-drilled disc brake rotor engineered to deliver consistent, reliable stopping power. Designed as a direct OE-replacement upgrade, this rotor installs without modifications and restores or improves upon factory braking performance.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to reduce heat stress and prevent cracking, allowing heat to escape efficiently and lowering overall rotor temperature during braking
• Enhanced Heat Dissipation: The drilled pattern promotes airflow across the rotor face, reducing brake fade under repeated or heavy braking conditions
• Corrosion-Resistant Coating: Silver zinc plating protects the hub, vanes, and non-braking surfaces from rust and corrosion, extending service life and maintaining appearance
• Direct-Fit Replacement: Engineered for a precise OEM-style fitment with no drilling, cutting, or modification required
• G3000 Cast Iron Construction: Manufactured from high-grade cast iron for durability and long-lasting performance
• Balanced and Road-Force Tested: Each rotor is precision-machined and tested to ensure smooth, vibration-free operation

The R1 Concepts RNC Series is ideal for drivers seeking a performance-oriented drilled rotor upgrade over stock. The silver zinc coating covers the rotor completely at time of delivery; during the bed-in process, the coating on the braking surface will wear off naturally, leaving the hub and vane structure protected. Always replace brake pads when installing new rotors and follow the proper break-in procedure for best results.
