R1 Concepts 623-32006L RNC Series Drilled Disc Brake Rotor - Rear Left

The R1 Concepts 623-32006L is a rear left (driver-side) drilled disc brake rotor from R1 Concepts' RNC Series, engineered as a direct-fit replacement for improved braking performance over factory rotors. Precision-drilled holes promote maximum heat dissipation, reduce brake fade, and help expel gas and debris from the rotor surface for consistent, confident stopping power.

Key Features:

• Drilled Design: Precision-drilled holes allow heat and gases to escape quickly, reducing rotor temperature and minimizing brake fade during demanding use
• Direct-Fit Replacement: Engineered to OEM specifications for hassle-free installation with no modifications required
• Zinc Coating: Protective zinc plating on the hat and non-swept surfaces guards against rust and corrosion, keeping the rotor looking clean behind the wheel
• Rear Left (Driver Side): Sold as a single rotor for the rear left position — confirm your required position before ordering
• High-Carbon Iron Construction: Cast from high-carbon iron for excellent thermal capacity, vibration dampening, and long service life
• OE-Style Vented Design: Internal vanes promote continuous airflow through the rotor for sustained cooling performance

R1 Concepts recommends replacing brake pads whenever installing new rotors and performing a proper bed-in procedure to ensure optimal contact between the pad and rotor surface. The 623-32006L is part of R1 Concepts' commitment to delivering performance-grade brake components at an accessible price point.
