R1 Concepts 623-03014L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-03014L RNC Series Drilled Brake Rotor delivers reliable stopping power with a performance-oriented cross-drilled design. Engineered to OEM specifications, this direct-fit replacement rotor installs without modification and is built from G3000 grade cast iron for consistent strength and durability across thousands of miles.

Key Features:

• Precision Cross-Drilled Holes: Countersunk and chamfered drill pattern maximizes heat dissipation, reducing rotor temperature and helping prevent brake fade during demanding driving conditions
• G3000 Cast Iron Construction: Premium iron grade provides exceptional stability, braking consistency, and long service life
• Zinc Plated Finish: Protective zinc coating shields the hub and inner vane structure from corrosion, extending the life and appearance of the rotor
• Double Disc Ground Surface: Promotes faster, more even brake pad bed-in for quieter, smoother stops from the start
• OEM Direct Fit: Manufactured to original equipment specifications — no drilling, cutting, or modifications required for installation
• Single Rotor: This listing covers one (1) rotor — the left/driver-side unit (suffix "L")

The RNC Series is an ideal upgrade or replacement for drivers seeking improved thermal management over a standard blank rotor. Always replace brake pads when installing new rotors, and follow the recommended bed-in procedure to maximize rotor and pad performance.
