R1 Concepts 623-20007L RNC Series Cross-Drilled Brake Rotor - Left

The R1 Concepts 623-20007L RNC Series Cross-Drilled Brake Rotor is a direct-fit, performance-grade replacement rotor engineered for improved stopping power and heat dissipation over stock. Designed as the left (driver) side front or rear rotor, it delivers a noticeable upgrade in both brake feel and rotor longevity compared to standard OEM units.

Key Features:

• Cross-Drilled Design: Precision-drilled holes allow heat, gas, and water to escape from the rotor surface, reducing brake fade and improving wet-weather performance
• RNC (Round Nail Cross-Drilled) Series: R1 Concepts' street/performance line balancing everyday drivability with enhanced thermal management
• Direct OEM Replacement: Manufactured to OEM specifications for a no-modification, bolt-on installation
• High-Carbon Gray Iron Construction: Provides consistent friction characteristics, reduced noise, and longer service life
• Zinc Dichromate Coating: Anti-rust coating on non-friction surfaces prevents premature corrosion and maintains a clean appearance
• Internal Vane Cooling: Vented rotor design promotes airflow through the rotor for continuous cooling during heavy braking
• Left Side (Driver Side) Application: Sold individually; confirm correct side before ordering

R1 Concepts rotors are manufactured in ISO-certified facilities and are rigorously tested to meet or exceed OEM performance standards. The 623-20007L is an ideal choice for drivers seeking a reliable, performance-enhanced brake rotor for street use.
