R1 Concepts 623-72025L RNC Drilled Disc Brake Rotor

The R1 Concepts 623-72025L RNC Drilled Brake Rotor is a precision-engineered replacement disc brake rotor designed to deliver confident, consistent stopping power. Built to OEM specifications, this rotor installs without modification and restores proper braking function to your vehicle.

R1 Concepts manufactures this rotor from G3000 grade cast iron, the same high-quality material specification used in original equipment rotors. The cross-drilled hole pattern improves airflow across the rotor face, helping to dissipate heat more rapidly during braking, reduce brake fade, and clear gas and debris from the pad-to-rotor contact surface.

Key Features:

• G3000 grade cast iron construction for strength and durability
• Cross-drilled design promotes heat dissipation and reduces brake fade
• Precision-machined to OEM specifications — direct bolt-on fitment, no modification required
• Silver zinc plating on non-friction surfaces for corrosion resistance and longer service life
• Balanced and tested for smooth, vibration-free braking performance
• Sold as a single rotor

R1 Concepts rotors are engineered for daily driving, light towing, and street performance applications. Proper break-in (bed-in) procedure is recommended upon installation to ensure even pad transfer and optimal braking performance.
