R1 Concepts 623-26006R RNC Series Drilled Brake Rotor

The R1 Concepts 623-26006R is an RNC Series drilled brake rotor engineered to deliver reliable stopping performance and improved heat dissipation over OEM rotors. R1 Concepts manufactures their rotors using high-carbon grey iron castings that resist warping and cracking under repeated thermal cycling, making them a trusted upgrade for daily drivers and performance enthusiasts alike.

The precision-drilled holes across the rotor face serve a dual purpose: they allow heat, gas, and brake dust to escape the rotor-pad interface, maintaining consistent bite and reducing brake fade during heavy use. The rotor surface is precision-machined to tight tolerances, ensuring smooth, vibration-free braking from the first stop.

Key Features:

• High-carbon grey iron construction for superior strength and heat resistance
• Precision-drilled holes for improved cooling, gas venting, and reduced brake fade
• Precision-machined rotor surface for smooth, vibration-free operation
• Direct OEM-replacement fit — no modifications required
• Zinc dichromate-plated hat and edges for corrosion resistance
• Balanced and tested to minimize runout and vibration

The 623-26006R is a direct replacement rotor designed for a straightforward, bolt-on installation. It is compatible with standard OEM-style brake pads and caliper hardware, making it an easy upgrade for those looking to improve braking performance without major modifications.
