R1 Concepts 623-56010L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-56010L is a cross-drilled disc brake rotor from the R1 RNC Series, designed as a direct-fit replacement rotor for the left (driver) side. Engineered to deliver consistent, reliable stopping power, this rotor is a performance-oriented upgrade over standard OEM smooth rotors.

Key Features:

• Cross-Drilled Design: Precision-drilled holes help dissipate heat, gas, and debris from the braking surface, reducing brake fade under repeated or heavy braking
• Direct-Fit Replacement: Designed to match OEM mounting specifications for a straightforward, no-modification installation
• Left-Side Application: Designated driver-side (left) rotor — sold individually
• Zinc Plating: Silver zinc-plated coating on the hat and vane areas protects against corrosion and rust for extended service life and clean appearance
• High-Carbon Iron Construction: Provides superior vibration dampening and thermal stability compared to standard cast iron rotors
• OEM Dimensions: Manufactured to OEM thickness and diameter tolerances for proper pad contact and pedal feel

The R1 Concepts RNC drilled brake rotor is an ideal choice for drivers seeking improved brake performance, heat management, and a sportier appearance behind the wheel. Compatible with OEM-style and performance brake pads.
