R1 Concepts 623-72051R RNC Series Drilled Disc Brake Rotor - Right/Passenger Side

The R1 Concepts 623-72051R is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement or performance upgrade over the factory rotor. The "-R" suffix designates this as the right (passenger) side rotor, sold individually.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote heat dissipation, reduce brake fade, and help expel water, gas, and debris from the rotor surface for consistent stopping power in all conditions
• Countersunk Drill Holes: Engineered to minimize heat stress concentration and reduce the risk of cracking under demanding use
• High-Carbon Gray Iron Construction: Delivers superior strength, vibration dampening, and long service life compared to standard cast iron rotors
• Corrosion-Resistant Coating: Zinc or e-coat finish applied to the non-friction surfaces protects against rust and corrosion, maintaining appearance and extending rotor life
• OEM-Style Direct Fit: Manufactured to match OEM mounting specifications for a straightforward, no-modification installation
• Balanced and Trued: Each rotor is precision-balanced and machined to tight tolerances to minimize vibration and pedal pulsation
• Right/Passenger Side (R): Sold as a single rotor — confirm quantity needed for your application

R1 Concepts RNC Series rotors are a trusted choice for drivers seeking a performance-oriented drilled rotor that improves upon stock braking without sacrificing daily drivability. Compatible brake pads should always be replaced alongside new rotors, and a proper bed-in procedure is recommended after installation for optimal performance.
