R1 Concepts 623-56017R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-56017R RNC Series Brake Rotor is a precision-engineered cross-drilled disc brake rotor designed to deliver enhanced stopping power and improved thermal management over stock rotors. Built to OEM specifications for a direct-fit, no-modification installation, this rotor is an ideal upgrade for drivers seeking improved braking performance in everyday street driving, light towing, and spirited driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat buildup on the rotor surface by dissipating heat efficiently, while minimizing the risk of cracking
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for superior durability, stability, and consistent braking performance
• Zinc Plated Corrosion Protection: A zinc plating coating is applied across the rotor hub and vane structure to resist rust and corrosion, extending rotor life and maintaining appearance
• OE Spec Direct Fit: Engineered to original equipment specifications — no modifications required for installation
• Improved Heat Dissipation: The drilled hole pattern promotes airflow across the rotor face, helping to reduce brake fade during repeated stops
• Vented Construction: Internal venting further aids in cooling the rotor under demanding braking conditions

Break-In Notice: Upon receipt, rotors are fully coated with a zinc finish. During the initial bed-in process, the coating on the braking surface will wear away as designed, leaving the hub and inner vane structure protected. Always follow a proper break-in procedure when installing new rotors, and replace brake pads at the same time as rotors for optimal performance.

The R1 Concepts 623-56017R is a reliable, performance-oriented replacement rotor backed by R1 Concepts' commitment to quality braking systems.
