R1 Concepts 623-27022L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-27022L RNC Series Drilled Brake Rotor is a high-performance replacement disc rotor engineered to deliver improved stopping power and thermal management over standard OEM rotors. Precision cross-drilled holes reduce heat buildup during heavy braking, channel away gases and debris from the pad surface, and help prevent brake fade during demanding driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are chamfered and countersunk to enhance ventilation, dissipate heat, and reduce the risk of cracking under stress
• G3000 Grade Cast Iron Construction: Manufactured from high-grade cast iron to OEM specifications for reliable fitment and consistent braking performance
• Zinc Plating Finish: Corrosion-resistant zinc coating protects the rotor hat and non-swept surfaces from rust and premature deterioration
• Direct-Fit Replacement: Engineered to match OEM dimensions and bolt patterns — no modifications required for installation
• Sold Individually: This listing is for a single rotor (left side), allowing targeted replacement as needed

The R1 Concepts RNC Series drilled brake rotor is an ideal upgrade for drivers seeking better heat dissipation and braking confidence over factory equipment, while maintaining a straightforward, bolt-on installation.
