R1 Concepts 623-03033L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-03033L RNC Series Drilled Brake Rotor is a precision-engineered replacement disc rotor designed to deliver reliable, high-performance stopping power. This is a single left-side (driver-side) rotor built to OEM specifications for a direct-fit, no-modification installation.

The RNC Series features precision cross-drilled holes with a countersunk design that promotes maximum heat dissipation, helps prevent rotor cracking, and reduces brake fade during repeated or demanding stops. The drilled pattern also aids in clearing water, dust, and debris from the braking surface for consistent pad contact and pedal feel.

Key Features:

• Precision Cross-Drilled Design — Countersunk drill holes dissipate heat efficiently and resist cracking under thermal stress
• G3000 Grade Cast Iron Construction — Premium cast iron compound meets or exceeds OEM standards for durability and performance
• Silver Zinc Plating — Corrosion-resistant coating protects the hub, hat, and vane structure from rust and extends rotor service life
• Direct OEM Replacement — Engineered to match factory specifications for easy bolt-on installation with no modifications required
• Left/Driver-Side Single Rotor — Sold individually; verify fitment with your vehicle application data
• Improved Ventilation — Vented internal vane design promotes airflow for continuous cooling during extended use

The R1 Concepts RNC Series is an excellent upgrade or replacement for drivers seeking improved heat management and dependable braking performance over standard OEM rotors. Compatible with OEM-style or performance brake pads.
