R1 Concepts 623-48041R RNC Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-48041R RNC Drilled Brake Rotor is a high-performance, cross-drilled disc brake rotor engineered for consistent stopping power and long-lasting durability. Manufactured to OEM specifications using G3000 grade cast iron, this rotor installs as a direct-fit replacement with no modifications required.

The cross-drilled hole pattern is precision-machined with countersunk edges to minimize heat stress and reduce the risk of cracking. By allowing hot gases and heat to escape from the rotor surface, the drilled design helps lower rotor operating temperatures and combat brake fade during demanding driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled and countersunk holes dissipate heat efficiently and help prevent brake fade
• G3000 Cast Iron Construction: OEM-grade iron formulation delivers excellent structural strength, stability, and braking consistency
• Zinc Plating Coating: Applied to the hat, vanes, and non-contact surfaces to resist corrosion and extend rotor lifespan
• Direct-Fit Replacement: Manufactured to OEM dimensional specifications for a hassle-free, no-modification installation
• Balanced and Tested: Each rotor is precision-balanced to minimize vibration and ensure smooth, quiet braking performance
• Suitable for Street and Light Performance Use: Ideal for daily driving, light towing, and spirited street performance

As with all new rotor installations, a proper brake bed-in (break-in) procedure is recommended to seat the pads evenly against the new rotor surface and achieve optimal performance. Always replace brake pads when installing new rotors.
