R1 Concepts 623-47066L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47066L is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement or performance upgrade. Cross-drilled holes allow heat and gases to dissipate quickly from the rotor surface, reducing brake fade and improving consistent stopping performance under a variety of driving conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes improve heat dissipation and help expel gas and debris from the rotor face for more consistent braking
• Direct-Fit Replacement: Engineered to OEM specifications for straightforward installation without modification
• Left/Driver-Side Fitment: This is a single rotor intended for the left (driver) side position
• High-Carbon Gray Iron Construction: Cast from high-quality iron for durability, reduced vibration, and longer service life
• Protective Coating: Anti-corrosion coating applied to non-friction surfaces to resist rust during storage and daily use
• OEM-Grade Balance: Precision-balanced to minimize vibration and pedal pulsation

R1 Concepts is a leading manufacturer of aftermarket and OEM-replacement braking components. The RNC Series drilled rotor delivers improved thermal performance over standard smooth rotors, making it a popular choice for drivers seeking enhanced braking feel and longevity.
