R1 Concepts 623-27044L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-27044L RnC Series Drilled Brake Rotor is a direct-fit, cross-drilled disc brake rotor engineered for reliable stopping performance and long-term corrosion resistance. Designed as a left (driver-side) replacement rotor, it is built to OEM specifications for a precise, no-modification installation.

R1 Concepts' RnC (Rust and Corrosion) Series rotors are manufactured from G3000 grade cast iron and treated with a protective zinc coating to guard against rust and corrosion on the hat, hub, and vane areas. The cross-drilled hole pattern improves heat dissipation and ventilation, helping to reduce brake fade during normal street driving.

Key Features:

• Cross-Drilled Design – Enhances airflow and heat dissipation to reduce brake fade
• G3000 Grade Cast Iron Construction – Provides strength, durability, and consistent performance
• Zinc Corrosion-Resistant Coating – Protects non-braking surfaces from rust and corrosion for improved longevity
• OEM Dimensions – Direct replacement fit with no modifications required
• Left Side (Driver Side) – Sold individually; designed specifically for the left/driver-side position
• Balanced and Road-Tested – Manufactured to minimize vibration and noise during braking

The R1 Concepts RnC Series is an excellent choice for drivers seeking an upgrade over worn OEM rotors without sacrificing daily drivability. Pair with compatible R1 Concepts brake pads for optimized braking performance and even pad wear.
