R1 Concepts 623-07001L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-07001L is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC (Race-N-Street Concepts) Series, designed to deliver upgraded stopping performance over stock replacement rotors. Built to OEM specifications for a direct-fit installation with no modifications required, this left-side rotor is a straightforward upgrade for drivers seeking improved braking response.

Key Features:

• Drilled Design: Precision cross-drilled holes promote heat dissipation, reduce brake fade, and help expel gas and moisture from the braking surface during hard stops
• G3000 Grade Cast Iron Construction: High-quality cast iron meets OEM material standards for durability and consistent thermal performance
• Zinc Plating: Corrosion-resistant zinc finish protects the non-braking surfaces from rust and extends rotor life
• OEM Direct-Fit: Engineered to match original equipment dimensions for bolt-on installation
• Left-Side Application: Designed specifically for the driver-side (left) position — part number suffix "L" denotes left-hand fitment
• Vented Construction: Internal vane ventilation channels promote continuous airflow to keep rotor temperatures in check during repeated braking

The R1 Concepts RNC Series drilled rotor is well-suited for street driving, light performance use, and daily commuting where enhanced thermal management and a clean appearance behind the wheel are priorities. Always replace brake pads when installing new rotors, and follow the recommended bed-in procedure for optimal performance and longevity.
