R1 Concepts 623-45045R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-45045R is a precision-engineered cross-drilled disc brake rotor from R1 Concepts' RNC Series, designed to deliver reliable stopping power as a direct OEM-style replacement. Manufactured to strict dimensional tolerances, this rotor installs in place of your factory unit with no modifications required.

Key Features:

• Cross-Drilled Design: Precision-drilled holes channel heat and gas away from the braking surface, reducing brake fade and improving pad bite during repeated stops
• OEM-Quality Fitment: Engineered to match original equipment dimensions for a straightforward, bolt-on installation
• Corrosion-Resistant Finish: Protective zinc coating applied to the hat, hub, and vane areas guards against rust and extends rotor service life
• Gray Iron Construction: Cast from high-quality gray iron for excellent thermal stability and consistent braking performance
• Balanced and Road-Force Tested: Each rotor is tested to ensure smooth, vibration-free braking with minimal noise
• Single Rotor (1-Piece): Sold individually — verify your required side before ordering

R1 Concepts rotors are manufactured using computer-aided design technology and advanced production methods to meet or exceed OEM standards. The 623-45045R is an ideal upgrade or replacement for drivers seeking improved thermal performance over a standard blank rotor without sacrificing daily-driver comfort or longevity.
