Key Features:

• Drilled Design: Precision cross-drilled holes promote rapid heat evacuation, reducing brake fade during repeated or heavy stops
• Direct OEM Replacement: Engineered to match factory mounting dimensions for a bolt-on installation
• Left/Driver Side Application: This unit (suffix "L") is specifically designed for the left, driver-side position
• Premium Construction: Manufactured from high-grade cast iron for durability and consistent braking performance
• Corrosion-Resistant Finish: Protective coating on non-friction surfaces helps resist rust and corrosion during storage and operation
• Balanced Performance: Suitable for street driving and light performance applications

The R1 Concepts RNC drilled rotor is an excellent choice for drivers looking to upgrade their braking system with improved thermal management and a cleaner, performance-oriented aesthetic. Always replace brake rotors in axle pairs for balanced and safe braking performance.
