R1 Concepts 623-20018R RNC Series Drilled Brake Rotor

The R1 Concepts 623-20018R RNC Series Drilled Brake Rotor is a precision-engineered replacement brake disc designed to deliver reliable stopping performance and improved heat dissipation over a standard solid rotor. The drilled pattern allows heat, gas, and debris to escape quickly from the braking surface, helping to maintain consistent pad contact and reduce brake fade during repeated stops.

Built from high-quality G3000-grade cast iron, this rotor meets or exceeds OEM specifications for dimensional accuracy, balance, and runout tolerance. The RNC (R1 Non-Coated) designation indicates a clean, uncoated finish on the braking surfaces, making it ready for immediate break-in and bedding with your brake pads.

Key Features:

• Drilled Design: Cross-drilled holes promote rapid heat and gas evacuation for reduced brake fade
• G3000 Cast Iron Construction: OEM-grade metallurgy ensures durability and consistent friction performance
• OEM-Equivalent Dimensions: Direct bolt-on fitment with no modifications required
• Precision Balanced: CNC-machined to tight runout tolerances for smooth, vibration-free braking
• RNC Finish: Clean, uncoated braking surface ready for immediate use
• Right-Side Rotor: Designated passenger-side fitment (suffix "R")

The R1 Concepts 623-20018R is an ideal upgrade or direct replacement for drivers seeking improved braking feel and thermal management compared to a standard OEM-style rotor. Always follow a proper break-in procedure when installing new rotors and pads to ensure optimal performance and longevity.
