R1 Concepts 623-03011R RNC Series Drilled Brake Rotor

The R1 Concepts 623-03011R is a drilled performance brake rotor from the RNC Series, engineered for drivers who demand reliable stopping power and improved thermal management. This rotor features precision-drilled holes across the rotor face to evacuate heat, gas, and brake dust — reducing brake fade and maintaining consistent pedal feel under demanding driving conditions.

Key Features:

• Drilled Design: Cross-drilled holes promote heat dissipation and gas venting, keeping rotor surface temperatures lower during aggressive braking
• Precision Machined: Computer-balanced and precision-machined to tight tolerances for smooth, vibration-free braking performance
• Corrosion-Resistant Coating: Anti-rust coating applied to non-friction surfaces helps extend rotor life and maintain clean appearance
• OE-Style Fitment: Designed as a direct bolt-on replacement, requiring no modifications for installation
• High-Carbon Steel Construction: Formulated for durability and consistent performance across a wide range of temperatures and driving conditions
• Right-Side Rotor: This is the right (passenger side) rotor — order in pairs for balanced braking performance

The R1 Concepts RNC Series is a popular choice for drivers seeking an upgrade over standard OEM rotors without moving to a full race-spec component. The drilled configuration pairs well with performance brake pads for a complete brake system upgrade.
