R1 Concepts 623-48023R RNC Series Drilled Brake Rotor

The R1 Concepts 623-48023R RNC Drilled Brake Rotor is a performance-grade disc brake rotor engineered to deliver improved stopping power and heat dissipation over standard OEM rotors. Designed as a direct-fit replacement, this rotor installs without modification for a straightforward upgrade to your vehicle's braking system.

R1 Concepts' cross-drilled rotor design features precision-drilled holes that are chamfered and counter-sunk to maintain structural integrity while enhancing airflow across the rotor face. This venting action helps reduce heat buildup during repeated braking, contributing to more consistent and fade-resistant performance.

Key Features:

• Cross-Drilled Design: Precision holes chamfered and counter-sunk to reduce heat buildup by up to 105°F while minimizing the risk of cracking
• G3000 Grade Cast Iron Construction: High-quality iron grade providing excellent stability, braking power, and long service life
• Silver Zinc Plated Coating: Corrosion-resistant finish protects the hub and vane structure for improved appearance and longevity
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter and smoother stops
• Direct-Fit Design: Built to OEM specifications — no drilling, cutting, or modification required for installation
• Single Rotor: Sold individually; verify quantity needed for your application

R1 Concepts rotors are manufactured by one of the automotive industry's leading brake specialists, with over 20 years of brake engineering experience. The 623-48023R is well suited for daily driving, light towing, and street performance use. Always follow the recommended break-in procedure when installing new rotors to ensure optimal pad bed-in and long-term braking performance.
