R1 Concepts 623-72034R RNC Series Drilled Disc Brake Rotor Right

The R1 Concepts 623-72034R is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement for the right side of compatible vehicles. Built to OEM specifications, this rotor installs without modification and delivers improved braking performance over stock components.

The cross-drilled hole pattern is a defining feature of this rotor, providing enhanced heat dissipation during repeated or hard braking events. By allowing hot gases and heat to escape the friction surface, the drilled design helps reduce brake fade and maintains consistent pedal feel under demanding conditions. The countersunk drill holes are engineered to minimize stress concentration and reduce the risk of cracking at the drill points.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote maximum heat dissipation and help expel gases and debris from the braking surface
• Direct-Fit Replacement: Engineered to OEM specifications for a bolt-on installation with no modifications required
• Right-Side Application: Sold as a single rotor for the right (passenger) side — MPN suffix "R" denotes right-hand fitment
• Corrosion-Resistant Finish: Zinc coating on the non-braking surfaces helps protect against rust and extends rotor appearance and service life
• G3000 Grade Cast Iron Construction: High-quality iron alloy provides the strength, thermal stability, and durability required for reliable everyday braking
• Vented Design: Internal vane structure promotes airflow through the rotor body to further aid cooling

The R1 Concepts 623-72034R RNC Series drilled brake rotor is a strong choice for drivers seeking a performance-oriented replacement rotor that improves upon OEM braking without requiring a full race-spec setup. Suitable for daily driving, light performance use, and vehicles where consistent, fade-resistant stopping power is a priority. Always replace brake pads when installing new rotors and follow proper bed-in procedures for optimal performance.
