R1 Concepts 623-72021R RNC Series Drilled Brake Rotor

The R1 Concepts 623-72021R RNC Series Drilled Brake Rotor is a precision-engineered replacement disc rotor designed to deliver reliable, consistent stopping performance. Sold as a single rotor for the right (passenger) side, this unit is built to OEM fitment specifications for a direct, no-modification installation.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to maximize heat dissipation, reduce thermal buildup, and help prevent rotor cracking under repeated braking cycles
• G3000 Grade Cast Iron Construction: High-quality cast iron provides the strength, durability, and thermal stability needed for dependable everyday braking performance
• Zinc Plated Finish: Corrosion-resistant zinc coating protects the rotor hat and non-swept surfaces from rust, extending the service life and maintaining a clean appearance
• OEM-Matched Specifications: Engineered to match factory dimensions and bolt patterns for a precise, hassle-free drop-in fit with no modifications required
• Improved Ventilation: Drilled holes promote airflow across the rotor face, helping to lower rotor temperatures and reduce brake fade during repeated or heavy stops
• Single Rotor — Right Side (Passenger): Sold individually; MPN suffix "R" denotes the right/passenger side fitment

The R1 Concepts 623-72021R is well-suited for daily driving applications where improved heat management and clean aesthetics are desired. As with any rotor replacement, it is recommended to replace brake pads simultaneously and follow a proper bed-in procedure to ensure optimal braking performance and pad seating.
