R1 Concepts 623-47070L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47070L is a precision-engineered drilled disc brake rotor from the RNC Series — R1 Concepts' dedicated cross-drilled rotor line designed for drivers who want improved braking performance and heat management over a standard OE replacement rotor.

Cross-drilled holes channel heat away from the rotor face, helping to reduce brake fade during repeated or heavy stops. The rotor is manufactured from a high-grade iron alloy and is mill-balanced for smooth, vibration-free operation right out of the box.

Key Features:

• Cross-drilled design for improved heat dissipation and reduced brake fade
• Countersunk drill holes help prevent rotor cracking under thermal stress
• Silver zinc plated coating protects against corrosion during storage and initial installation
• Mill-balanced construction minimizes vibration and pedal pulsation
• Manufactured to OE thickness specifications for direct-fit installation
• Quality validated for proper metallurgy and correct brake plate thickness
• Single rotor — left side (L)

The silver zinc coating on the braking surface will wear off naturally during the initial break-in period, leaving the hub and vane structure protected. A proper rotor and pad bed-in procedure is recommended after installation to achieve optimal braking performance and maximum rotor life.
