R1 Concepts 623-21047R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-21047R is a drilled disc brake rotor from R1 Concepts' RNC Series, engineered for improved braking performance and thermal management over OEM replacement rotors. Precision-machined from high-grade cast iron, this rotor features a drilled pattern designed to reduce heat buildup, minimize brake fade, and expel gas and debris from the rotor surface during heavy braking.

Key Features:

• Drilled pattern for enhanced heat dissipation and reduced brake fade
• Precision-machined from high-carbon cast iron for durability and consistent performance
• Zinc-plated or e-coated non-friction surfaces to resist corrosion and extend rotor life
• Balanced and computer-tested for vibration-free braking
• OE-style hat and hub dimensions for direct-fit installation
• Meets or exceeds OEM specifications for safe, reliable stopping power

The R1 Concepts RNC Series drilled rotor is a direct OEM replacement upgrade, offering improved performance characteristics over a standard smooth rotor. It is designed for straightforward bolt-on installation with no modifications required.
