R1 Concepts 623-55000R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-55000R RNC Series Drilled Brake Rotor is a precision-engineered disc brake rotor designed to deliver enhanced stopping performance over standard OEM rotors. Built to direct-fit OEM specifications, this rotor installs without modification for a straightforward replacement experience.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to maximize heat dissipation, reduce rotor temperature, and prevent stress cracking during heavy braking
• G3000 Grade Cast Iron Construction: Manufactured from high-grade cast iron for durability, consistent friction, and long service life
• Zinc Plating: Protective zinc coating applied to non-braking surfaces guards against rust and corrosion, maintaining appearance and longevity
• OEM Direct-Fit: Engineered to OEM specifications — no modifications, drilling, or cutting required for installation
• Improved Heat Management: Drilled venting helps channel heat and gases away from the pad-to-rotor contact surface, reducing brake fade under repeated or hard stops
• Part Number: 623-55000R

The R1 Concepts RNC Series drilled rotor is an ideal upgrade for drivers seeking improved thermal performance and a cleaner appearance over stock rotors. Always replace brake pads when installing new rotors, and follow the recommended bed-in procedure to ensure optimal performance and longevity.
