R1 Concepts 623-20003R RNC Series Drilled Brake Rotor

The R1 Concepts 623-20003R is a RNC Series drilled brake rotor engineered for reliable, high-performance stopping power. Manufactured to precise OEM dimensional specifications, this rotor is a direct bolt-on replacement that restores braking confidence without modification.

R1 Concepts RNC rotors feature a precision-drilled pattern that serves dual purposes: reducing unsprung weight and promoting rapid heat dissipation during repeated braking events. The drilled holes also help evacuate gases, water, and debris from the rotor face, maintaining consistent pad-to-rotor contact for reliable, fade-resistant braking performance.

Key Features:

• Drilled Design: Precision-drilled holes improve heat venting and wet-weather braking performance
• OEM Fitment: Engineered to OEM dimensional specifications for a direct, no-modification installation
• High-Carbon Alloy Iron: Premium metallurgy for durability, reduced vibration, and long rotor life
• Balanced Construction: Computer-balanced rotor assembly minimizes vibration and brake pulsation
• Corrosion-Resistant Finish: Protective coating on non-friction surfaces resists rust during storage and initial installation
• Manufacturer Part Number: 623-20003R

The R1 Concepts 623-20003R is an ideal upgrade or replacement for drivers seeking improved braking performance over a standard OEM rotor. Compatible with a range of street and light performance applications, this rotor pairs well with R1 Concepts or other quality brake pads for optimized system performance.
