R1 Concepts 623-47062L RNC Drilled Brake Rotor - Left

The R1 Concepts 623-47062L is a precision-engineered drilled disc brake rotor designed as a direct-fit replacement for the left (driver) side. Built to OEM specifications using G3000 grade cast iron, this rotor delivers reliable, consistent stopping power without requiring any vehicle modifications for installation.

Cross-drilled holes are countersunk and chamfered to maximize heat dissipation while reducing the risk of stress cracking — a key advantage over non-countersunk designs. The drilled pattern helps evacuate heat, gas, and brake dust from the rotor surface, maintaining firm, fade-resistant braking performance during repeated stops.

Key Features:

• Cross-Drilled Pattern — Countersunk and chamfered holes reduce heat buildup by improving airflow across the rotor face
• G3000 Cast Iron Construction — Meets OEM iron grade specifications for strength, stability, and consistent performance
• Zinc Plated Coating — Corrosion-resistant finish protects the hub and vane structure from rust and premature wear
• Direct-Fit Design — Manufactured to OEM dimensions; no cutting, drilling, or modifications required
• Left Side (Driver Side) — Sold individually; designed specifically for the left/driver-side position

A proper brake bed-in procedure is recommended after installation to ensure even pad transfer and optimal rotor performance. Always replace brake pads when installing new rotors for best results.
