R1 Concepts 623-72024L RNC Series Drilled Brake Rotor - Left/Driver Side

The R1 Concepts 623-72024L RNC Series Drilled Brake Rotor is a precision-engineered performance brake disc designed as a direct-fit replacement for the left (driver) side. Built to meet or exceed OEM specifications, this drilled rotor delivers improved heat dissipation and consistent stopping power for daily driving, street performance, and light towing applications.

Key Features:

• Cross-Drilled Design: Precision-drilled holes reduce rotor temperatures by channeling heat away from the braking surface, improving fade resistance during repeated or hard stops
• Chamfered and Counter-Sunk Holes: Each drill hole is chamfered to maintain structural integrity and counter-sunk to help prevent cracking during the bed-in process
• G3000 Grade Cast Iron Construction: Manufactured from G3000 grade cast iron for excellent strength, stability, and long-term durability
• Zinc Plated Corrosion Protection: Special zinc plating protects the hub, hat, and vane structure from rust and corrosion for improved longevity and appearance
• Non-Directional Surface Finish: Prepared with a non-directional finish to promote faster, more even brake pad bed-in and quieter, smoother stops
• Direct-Fit Replacement: Engineered to OEM specifications for a no-modification, bolt-on installation
• Left/Driver Side Fitment: This is a single rotor for the left (driver) side — sold individually

R1 Concepts rotors are designed and tested to provide reliable braking performance across a wide range of driving conditions. Always replace brake pads when installing new rotors for optimal performance and safety.
