R1 Concepts 623-27013L RNC Series Drilled Brake Rotor

The R1 Concepts 623-27013L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver confident, consistent stopping power. Manufactured using high-carbon grey iron, this rotor offers superior heat dissipation and fade resistance compared to standard OE-style rotors, making it well-suited for daily driving and spirited street use.

The drilled hole pattern reduces rotor weight and provides additional surface area for heat and gas evacuation, helping to maintain brake pad bite and reduce brake fade during repeated stops. Each rotor is precision-balanced and machine finished to OE specifications for a straightforward, direct-fit installation with no modification required.

Key Features:

• Drilled rotor design for enhanced cooling and reduced weight
• High-carbon grey iron construction for durability and heat management
• Precision-machined to OE tolerances for direct-fit replacement
• Balanced for smooth, vibration-free braking performance
• Corrosion-resistant coating on non-swept surfaces to resist rust
• Left-side (driver side) fitment — verify application before ordering

R1 Concepts is a California-based brake specialist known for producing performance brake components that meet or exceed OEM standards. The RNC (Rotor — Non-Coated swept surface) line is engineered for drivers who want a performance upgrade over basic stock rotors without sacrificing everyday drivability.
