R1 Concepts 623-16004L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-16004L is a RNC Series drilled brake rotor engineered for drivers seeking improved braking performance over standard OEM rotors. Precision-drilled holes across the rotor face promote continuous airflow and heat dissipation, reducing brake fade during sustained or aggressive braking situations.

Key Features:

• Drilled Rotor Design: Cross-drilled holes aid in heat ventilation, helping to maintain consistent stopping power and extend brake pad life
• G3000 Grade Cast Iron Construction: Manufactured to OEM-equivalent metallurgical standards for durability and reliable performance
• Zinc Plated Finish: Protective zinc coating guards against rust and corrosion, keeping the rotor looking clean and lasting longer
• OEM Fitment Specifications: Designed to direct-fit OEM mounting points with no modification required
• Left-Side Application: This part number (623-16004L) is specifically the left (driver's side) rotor
• Vented Design: Internal vane structure maximizes thermal management during heavy braking cycles

R1 Concepts RNC Series rotors are a direct OEM replacement upgrade, offering enhanced stopping performance and corrosion resistance for everyday driving and light performance use. This rotor is sold individually.
