R1 Concepts 623-03039R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-03039R RNC Series Drilled Brake Rotor delivers reliable stopping performance and enhanced thermal management in a direct-fit replacement design. Engineered as a precision drop-in replacement, this rotor requires no modifications and is built to restore or exceed original braking performance.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote maximum heat dissipation, reducing rotor temperatures and minimizing brake fade under demanding driving conditions
• Countersunk Drill Holes: Holes are countersunk to relieve stress concentrations, helping to prevent cracking and extend rotor service life
• Silver Zinc Plated Coating: Corrosion-resistant zinc plating protects non-braking surfaces from rust, improving appearance and longevity
• Direct-Fit Replacement: Engineered for a precise OEM-style fit with no cutting, drilling, or modification required
• High-Carbon Iron Construction: Cast from quality iron for consistent performance, noise reduction, and durability
• G3000 Grade Material: Meets or exceeds OEM material specifications for reliable everyday and performance use

The R1 Concepts RNC Series rotor is a trusted upgrade for drivers seeking improved braking confidence and durability over stock rotors. When installing new rotors, always replace brake pads at the same time and follow the recommended bed-in procedure to ensure optimal pad-to-rotor contact and long-term performance.
