R1 Concepts 623-01011R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-01011R RNC Series Drilled Brake Rotor delivers reliable stopping performance with a precision-drilled design engineered to meet or exceed OEM specifications. Built from high-grade G3000 cast iron, this rotor provides consistent, fade-resistant braking for everyday street driving and light performance use.

Key Features:

• Precision Cross-Drilled Design: Drilled holes improve ventilation, dissipate heat more efficiently, and help evacuate gas and debris from the braking surface for consistent pad contact
• G3000 Grade Cast Iron Construction: High-quality iron alloy delivers the strength, thermal stability, and longevity demanded by OEM and performance applications
• Zinc Plated Finish: Protective zinc coating guards against rust and corrosion, extending rotor life and maintaining a clean appearance behind the wheel
• OEM-Matched Specifications: Engineered to direct-fit OEM mounting points — no modifications or adapters required for installation
• Balanced and Precision Machined: Each rotor is precisely machined and balanced to minimize vibration and eliminate brake pedal pulsation
• Countersunk Drill Holes: Countersunk hole design reduces stress concentration at each drill point, helping prevent cracking under repeated thermal cycling

The R1 Concepts RNC Series drilled rotor is an excellent upgrade or direct replacement for worn OEM rotors, offering improved thermal performance and a more aggressive appearance. Compatible with standard OEM-style brake pads, this rotor is a straightforward drop-in solution for drivers seeking dependable braking with added heat management.
