R1 Concepts 623-47032L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-47032L RNC Series Drilled Brake Rotor is a direct-fit, high-performance replacement rotor engineered for drivers who demand reliable stopping power and improved thermal management. The "L" suffix designates this as the left-side (driver's side) rotor.

Key Features:

• Cross-Drilled Design: Precisely machined drill holes dissipate heat, gases, and water rapidly from the rotor surface, reducing brake fade under demanding conditions.
• Zinc-Plated Finish: Protective zinc coating guards the hat, vanes, and non-braking surfaces against rust and corrosion for improved longevity and appearance.
• Double Disc Ground Surface: The braking surface is double disc ground to tight tolerances, promoting faster, more even brake pad bed-in and quieter, smoother stops.
• OEM-Style Direct Fitment: Designed as a precise drop-in replacement — no drilling, cutting, or modification required.
• Vented Construction: Internal vane structure promotes continuous airflow through the rotor, actively cooling the braking surface during repeated stops.
• G3000 Metallurgy: Cast from premium G3000 gray iron for consistent friction characteristics, high durability, and stable performance across a wide temperature range.

The R1 Concepts RNC Series rotor is an ideal upgrade for daily drivers and enthusiasts seeking improved braking performance over standard OEM rotors. Compatible with OEM-style brake calipers and brackets. Always replace rotors in axle pairs and perform a proper brake bed-in procedure after installation.
