The R1 Concepts 623-03022L RNC Series Drilled Brake Rotor is a high-performance, cross-drilled disc brake rotor engineered as a direct OEM replacement with enhanced heat dissipation and corrosion resistance. Designed for drivers seeking a reliable upgrade over factory brake components without requiring any modifications, this rotor delivers consistent, confident stopping power.

Key Features:

• G3000 Grade Cast Iron Construction – Premium-grade cast iron meets OEM dimensional specifications for precise, drop-in fitment
• Cross-Drilled Design – Precision-drilled holes are chamfered and countersunk to reduce heat buildup, prevent cracking, and promote a smoother bed-in process
• Zinc Plating Finish – Protective zinc coating guards the rotor's non-braking surfaces against rust and corrosion for improved longevity and appearance
• OEM-Spec Dimensions – Built to exact factory tolerances; no cutting, grinding, or modification required for installation
• Left/Driver-Side Application – The "L" suffix designates this as the left (driver) side rotor; sold individually
• Improved Thermal Management – Drilled venting reduces rotor surface temperature for fade-resistant performance under repeated braking

The R1 Concepts RNC series is ideal for daily drivers and street performance enthusiasts looking for a dependable, budget-friendly brake rotor upgrade. Pair with R1 Concepts brake pads for a complete, optimized braking system.
