R1 Concepts 623-48034R RNC Series Drilled Disc Brake Rotor - Right

The R1 Concepts 623-48034R RNC Series Drilled Brake Rotor is a precision-engineered replacement disc brake rotor designed for drivers who want improved braking performance over a standard blank rotor. The cross-drilled hole pattern reduces heat buildup during aggressive braking, helps evacuate gases and debris from the pad-to-rotor contact surface, and contributes to a cleaner, more consistent brake feel.

R1 Concepts manufactures this rotor from high-carbon grey iron for maximum durability and thermal stability. A silver zinc dichromate coating is applied to the non-friction surfaces, protecting the hub, hat, and vane structure from corrosion and keeping the rotor looking clean behind the wheel. The braking surface coating wears away naturally during the break-in process, which is normal and expected.

Key Features:

• Cross-drilled hole pattern for improved heat dissipation and gas/debris evacuation
• Silver zinc dichromate coating on non-braking surfaces for corrosion resistance
• High-carbon grey iron construction for strength and thermal stability
• Direct OE-style fitment — no modifications required
• Right (passenger) side application — sold individually
• Manufactured to strict dimensional tolerances for proper pad contact and minimal runout

This rotor is part of R1 Concepts' RNC Series, which focuses on the drilled pattern without slotting, making it an ideal upgrade for daily drivers and light performance use. Always replace brake rotors in axle pairs and perform a proper bed-in procedure after installation to ensure optimal performance and longevity.
