R1 Concepts 623-76056R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-76056R is an RNC Series cross-drilled disc brake rotor engineered for drivers who demand reliable, consistent stopping performance. Manufactured from high-grade G3000 cast iron, this rotor is built to OEM dimensional specifications for a direct-fit, no-modification installation.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are chamfered and countersunk to reduce heat buildup, improve ventilation, and help prevent cracking during the bed-in process
• G3000 Cast Iron Construction: High-grade iron provides excellent strength, thermal stability, and long service life
• Zinc Plating Finish: Special zinc coating provides corrosion protection on non-braking surfaces, helping the rotor resist rust and maintain appearance
• OEM-Spec Dimensions: Engineered to factory specifications for a direct-fit replacement — no drilling, cutting, or modification required
• Heat Dissipation: Drilled holes reduce rotor operating temperature for more consistent brake feel and reduced fade under repeated stops
• Vented Construction: Internal vane design promotes airflow through the rotor for enhanced cooling performance

The R1 Concepts RNC Series drilled rotor is ideal for street driving and light performance use, offering a meaningful upgrade over worn OEM rotors. Sold individually — confirm quantity requirements before ordering.
