R1 Concepts 623-54129R RNC Series Drilled Brake Rotor

The R1 Concepts 623-54129R RNC Series Drilled Brake Rotor is a precision-engineered replacement disc rotor designed to deliver reliable stopping power and extended service life. Manufactured by R1 Concepts — a leading producer of performance braking components — this rotor is built to match or exceed OEM fitment standards while offering improved heat management through its cross-drilled design.

The drilled pattern promotes faster heat dissipation from the rotor surface, helping reduce brake fade during repeated or demanding stops. A silver zinc plated coating protects the non-braking surfaces from corrosion, preserving appearance and longevity. During the initial break-in period, the coating on the pad contact surface will wear away naturally, which is normal and expected.

Key Features:

• Cross-drilled rotor design for improved heat dissipation and reduced brake fade
• Silver zinc plated coating on hub and vane structures for corrosion resistance
• Precision machined to OEM specifications for direct-fit installation
• Chamfered drill holes to reduce stress cracking potential
• Designed for street and daily driving applications

This rotor is sold as a single unit. A proper break-in procedure is recommended after installation to ensure even pad transfer and optimal braking performance.
