R1 Concepts 623-47010R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47010R is a drilled disc brake rotor from R1 Concepts' RNC (R1 Neuston Coated) Series, engineered to deliver improved braking performance and extended rotor life over standard OE replacement rotors. The precision-drilled holes across the rotor face allow hot gases and heat to escape quickly during heavy braking, reducing brake fade and improving pad bite for more confident stopping power.

The RNC Series features R1 Concepts' proprietary Neuston Coat finish — a corrosion-resistant coating applied to the non-contact surfaces of the rotor (hat, edges, and vanes) that protects against rust and keeps the rotor looking clean behind the wheel. The friction surface is left uncoated for immediate pad-to-rotor contact right out of the box.

Key Features:

• Drilled rotor design for improved heat dissipation and reduced brake fade
• Proprietary Neuston Coat (NCC) corrosion-resistant coating on non-contact surfaces
• Premium G3000 gray iron casting for durability and consistent braking
• Precision-balanced for smooth, vibration-free performance
• Direct OE replacement — no modifications required for installation
• Manufactured to strict dimensional tolerances for proper fitment and pad contact

The R1 Concepts 623-47010R is a direct-fit replacement rotor designed for straightforward installation using standard hand tools. It is an ideal upgrade for drivers seeking better thermal management and a cleaner appearance compared to bare, uncoated OE rotors.
