R1 Concepts 623-40109R RNC Series Drilled Brake Rotor

The R1 Concepts 623-40109R RNC Series Drilled Brake Rotor is a high-performance replacement rotor engineered to deliver improved stopping power and consistent braking performance. Featuring precision-drilled holes across the rotor face, this design promotes rapid heat dissipation, reduces brake fade during demanding driving conditions, and helps expel gas and debris from between the pad and rotor surface for a cleaner, more responsive bite.

R1 Concepts manufactures this rotor to meet or exceed OEM specifications, ensuring a direct bolt-on fitment with no modifications required. The rotor is constructed from premium G3000-grade cast iron for durability and long service life, and features a non-directional finish that is compatible with a wide range of brake pad compounds.

Key Features:

• Drilled Design: Cross-drilled holes promote heat dissipation and reduce brake fade under heavy braking
• G3000 Cast Iron Construction: Premium-grade material for strength, longevity, and consistent thermal performance
• OEM-Quality Fitment: Engineered to direct-replace the factory rotor with no modifications needed
• Corrosion-Resistant Coating: Protective zinc dichromate coating on non-friction surfaces helps resist rust and corrosion
• Precision Machined: Tight tolerances ensure minimal runout for smooth, vibration-free braking
