R1 Concepts 623-72060L RNC Series Cross-Drilled Brake Rotor - Left

The R1 Concepts 623-72060L is a performance-grade cross-drilled disc brake rotor from R1 Concepts' RNC Series, engineered to deliver upgraded stopping power over standard OEM rotors. This is a single left/driver-side rotor designed as a direct-fit replacement requiring no modifications for installation.

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 heavy braking
• Enhanced Heat Dissipation: The drilled pattern improves airflow across the rotor face, reducing brake fade during repeated or hard stops
• Corrosion-Resistant Coating: Silver zinc-plated finish protects the rotor hub and vane structure from rust and corrosion, extending service life and maintaining appearance
• Direct-Fit Replacement: Engineered to OEM specifications for a bolt-on installation with no drilling, cutting, or modification required
• High-Carbon Construction: Manufactured from premium high-carbon iron for improved durability, noise reduction, and consistent friction surface performance

R1 Concepts recommends replacing brake pads whenever installing new rotors, and following a proper bed-in procedure to achieve optimal performance and maximum rotor life. This rotor is sold as a single unit (left side).
