R1 Concepts 623-31013L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-31013L is a RNC Series drilled brake rotor designed as a direct OEM replacement with enhanced performance characteristics. Engineered for drivers seeking improved braking response over a standard solid rotor, this left-side rotor features precision-drilled holes that help dissipate heat, reduce brake fade, and evacuate gas and debris from the rotor surface during braking.

Key Features:

• Drilled design promotes heat dissipation and reduces brake fade during repeated or hard stops
• Left-side application (driver side on most vehicles) — sold individually
• Direct OEM fit — no modifications required for installation
• High-carbon content iron construction for durability and improved bite with brake pads
• Zinc dichromate coating on non-swept surfaces to resist corrosion during storage and operation
• Precision machined to meet or exceed OEM dimensional tolerances for proper fitment and runout specs
• Compatible with R1 Concepts brake pads and most OEM and aftermarket pad compounds

The R1 Concepts RNC line offers an affordable entry point into drilled performance rotors, making it an ideal upgrade for daily drivers and light performance applications. As with all brake components, professional installation is recommended.
