R1 Concepts 623-74031L RNC Cross-Drilled Performance Brake Rotor

The R1 Concepts 623-74031L RNC Cross-Drilled Brake Rotor is a high-performance direct-fit replacement rotor engineered to deliver improved stopping power and thermal management over a standard OEM rotor. Designed for drivers seeking an upgrade in braking performance without sacrificing daily-driver comfort, this drilled rotor is a straightforward bolt-on replacement.

Key Features:

• Cross-Drilled Design: Precision-drilled holes across the rotor face allow heat, gas, and moisture to escape from the braking surface, reducing brake fade under demanding conditions
• Silver Zinc Plating: Corrosion-resistant zinc coating protects the rotor hub, vanes, and non-swept surfaces from rust and oxidation, extending rotor life and improving appearance
• OEM-Quality Metallurgy: Cast from high-grade G3000 iron for consistent hardness, thermal stability, and long service life
• Direct OEM Replacement: Engineered to match factory specifications for a precise, no-modification installation
• Balanced and Mill-Finished: Each rotor is precision-balanced and finished to minimize vibration and pedal pulsation
• Part Number: 623-74031L (Left/Driver Side)

A proper bed-in procedure is recommended after installation to seat the brake pads evenly and achieve optimal braking performance. Compatible with R1 Concepts brake pads as well as most OEM-equivalent pad compounds.
