R1 Concepts 623-54198R RNC Series Drilled Brake Rotor

The R1 Concepts 623-54198R RNC Series Drilled Brake Rotor delivers enhanced stopping performance for street and performance driving applications. Engineered with precision drilled holes across the rotor face, this rotor promotes efficient heat dissipation, reduces brake fade, and helps expel gases and debris that can build up between the pad and rotor surface during heavy braking.

Key Features:

• Drilled Design: Cross-drilled holes improve ventilation and thermal management, keeping brake temperatures in check during demanding use
• RNC Series Construction: Manufactured from high-carbon gray iron for improved rigidity, reduced vibration, and longer service life compared to standard cast iron rotors
• Precision Machined: Computer-balanced and precision machined to tight tolerances for smooth, vibration-free braking and minimal runout
• Corrosion-Resistant Coating: Non-braking surfaces feature a protective coating to resist rust and maintain a clean appearance
• Direct OE Replacement: Designed as a direct bolt-on replacement for a straightforward installation with no modifications required
• Performance Street Use: Ideal for drivers seeking improved braking feel and thermal performance over stock rotors

The R1 Concepts 623-54198R is a right-side (R suffix) rotor, sold individually. Always replace brake rotors in axle pairs and pair with compatible brake pads for optimal braking system performance and safety.
