R1 Concepts 623-21049R RNC Series Drilled Brake Rotor

The R1 Concepts 623-21049R RNC Series Drilled Brake Rotor is a performance-grade replacement disc rotor engineered to deliver improved stopping power and thermal management over a standard OEM rotor. Cross-drilled holes reduce heat buildup on the rotor surface and help channel away gases, water, and debris during braking for more consistent pedal feel in all conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes reduce rotor surface heat and improve wet-weather braking performance by quickly evacuating water and debris
• Chamfered Drill Holes: Countersunk and chamfered cross-drill pattern minimizes stress concentration to reduce the risk of cracking under repeated thermal cycling
• Corrosion-Resistant Coating: Silver zinc plating protects the non-braking surfaces, hub, and vanes from rust and corrosion for a longer service life and cleaner appearance
• G3000 Grade Cast Iron Construction: Premium cast iron formulation meets or exceeds OEM specifications for durability, friction compatibility, and noise dampening
• OEM-Spec Fitment: Manufactured to direct-fit, no-modification-required specifications for straightforward installation
• Direct Replacement: Sold as a single rotor (right side)

The R1 Concepts RNC Series drilled brake rotor is a reliable upgrade for drivers seeking better heat dissipation and improved braking response compared to a standard blank rotor. Compatible with R1 Concepts ceramic and performance brake pads for a complete braking system upgrade.
