R1 Concepts 623-03036L RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-03036L RNC Series Drilled Brake Rotor is a precision-engineered replacement disc brake rotor designed to deliver consistent, reliable stopping power. Featuring a cross-drilled rotor face, this rotor improves heat dissipation and helps reduce brake fade during repeated or heavy braking applications.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to minimize heat stress and prevent cracking while allowing heat and gases to escape efficiently
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for strength, durability, and OEM-comparable performance
• Zinc Plated Finish: Silver zinc coating protects against corrosion, extending rotor life and maintaining appearance
• Direct-Fit Replacement: Built to OEM specifications for a no-modification, bolt-on installation
• Left/Driver Side: This part number (623-03036L) is specifically the left-side rotor
• Vented Design: Internal venting channels promote airflow between rotor faces for continuous cooling during use

The R1 Concepts RNC Series drilled brake rotor is an ideal upgrade or direct replacement for drivers seeking improved thermal management and consistent braking performance over standard solid rotors. Sold individually.
