R1 Concepts 623-32006R RNC Cross-Drilled Brake Rotor

The R1 Concepts 623-32006R RNC Brake Rotor is a precision cross-drilled disc brake rotor engineered to deliver improved stopping performance over stock rotors. Built to OEM dimensional specifications, this rotor installs without modification for a direct-fit replacement experience.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat stress and prevent cracking, while allowing heat and gases to escape efficiently for improved fade resistance
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for excellent durability, thermal stability, and consistent braking performance
• Zinc Plated Finish: Full-rotor zinc coating protects the hub, vanes, and hat from corrosion — extending service life and maintaining a clean appearance behind the wheel
• OEM-Spec Dimensions: Manufactured to original equipment specifications for direct fitment with no modifications required
• Double Disc Ground Braking Surface: The friction surface is double-disc ground to promote a faster, more even brake pad bed-in and deliver quieter, smoother stops from day one
• Improved Heat Dissipation: Cross-drilled holes reduce rotor operating temperatures, helping maintain consistent pedal feel under repeated or heavy braking

The R1 Concepts RNC rotor is an ideal upgrade for drivers seeking enhanced braking over factory equipment without sacrificing street comfort or ride quality. As with all R1 Concepts rotors, a proper brake pad bed-in procedure is recommended after installation for optimal performance and longevity.
