R1 Concepts 623-72009L RNC Series Drilled Disc Brake Rotor Left

The R1 Concepts 623-72009L RNC Series Drilled Brake Rotor is a precision-engineered performance disc brake rotor designed as a direct-fit replacement for vehicles requiring this left-side application. Part of R1 Concepts' RNC line, this rotor features a cross-drilled pattern engineered to improve braking performance over standard OEM rotors.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote rapid heat dissipation, reducing brake fade during sustained or high-demand braking
• Countersunk Drill Holes: Engineered to minimize stress concentration and reduce the risk of cracking at the hole edges
• Direct-Fit Replacement: Manufactured to OEM specifications for bolt-on installation with no modifications required
• Left-Side (Driver Side) Application: Sold individually as a single left-side rotor — confirm your vehicle's fitment before purchase
• Corrosion-Resistant Coating: Protective finish applied to the hat and non-friction surfaces to inhibit rust and extend service life
• Vented Construction: Internal vane design maintains airflow through the rotor for consistent thermal management

R1 Concepts manufactures its rotors to meet or exceed OEM standards, making the 623-72009L a reliable upgrade for drivers seeking improved stopping performance and a cleaner aesthetic behind the wheel. Always replace brake pads when installing new rotors, and follow proper bed-in procedures to ensure optimal performance and longevity.
