R1 Concepts 623-32004L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-32004L is a single left-side (driver side) drilled brake rotor from R1 Concepts' RNC eLINE Black Series. Engineered to deliver improved stopping performance over standard OEM rotors, this rotor features precision cross-drilled holes that enhance heat dissipation, reduce brake fade, and help expel gas and debris from the braking surface during use.

Key Features:

• Cross-Drilled Design: Precision-drilled holes improve ventilation and thermal management, reducing heat buildup during repeated braking
• Black Zinc Coating: Corrosion-resistant black zinc finish protects non-friction surfaces from rust and improves appearance behind the wheel
• G3000 Cast Iron Construction: High-grade G3000 cast iron meets or exceeds OEM specifications for strength and consistent braking performance
• OEM Fitment: Engineered to OEM specifications for a direct bolt-on replacement with no modifications required
• Left Side (Driver Side): This is a single rotor replacement for the left/driver front or rear position — verify your application before ordering
• Vented Rotor Design: Internal vane structure promotes airflow through the rotor for sustained cooling performance

The R1 Concepts RNC eLINE Black Series is designed for drivers seeking an upgrade over stock rotors with enhanced thermal performance and a more aggressive look. Compatible with OEM brake pads and R1 Concepts performance pad lines.
