R1 Concepts 623-48063L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-48063L is a RNC Series cross-drilled brake rotor engineered for drivers who demand reliable stopping power and long-lasting durability. Manufactured to OEM specifications, this left-side rotor installs without modification and restores braking performance equal to or better than the factory original.

Key Features:

• Cross-Drilled Design: Precision-drilled holes enhance ventilation, dissipate heat faster, and prevent brake fade under demanding driving conditions
• G3000 Grade Cast Iron Construction: High-quality cast iron provides exceptional strength, wear resistance, and consistent braking performance
• Silver Zinc Plated Coating: Protects the rotor hub and vanes from corrosion, extending rotor life and improving overall appearance
• OEM-Matched Specifications: Engineered to factory dimensions for a direct-fit, no-modification installation
• Left-Side Fitment (L): Designed specifically for the driver-side position — verify application fitment before ordering
• Countersunk Drill Holes: Reduces stress concentration at each hole to help prevent cracking during heavy use

R1 Concepts rotors are manufactured with state-of-the-art technology to deliver high-quality stopping power at an affordable price point. The RNC Series is an ideal upgrade or direct replacement for worn factory rotors, offering improved thermal management and a clean, performance-inspired appearance.
