R1 Concepts 623-03049L RNC Series Drilled Brake Rotor

The R1 Concepts 623-03049L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver confident stopping power and improved thermal management over stock brake components. Crafted from high-carbon grey iron, this rotor provides excellent heat dissipation and fade resistance under demanding driving conditions.

The drilled pattern across the rotor face allows hot gases, heat, and debris to escape quickly, keeping brake pad bite consistent and reducing the risk of brake fade during repeated hard stops. The rotor is precision-balanced and features a non-directional finish on the braking surface for immediate pad bedding and optimal contact from the first stop.

Key Features:

• Drilled rotor design for improved heat dissipation and gas venting
• High-carbon grey iron construction for strength and reduced noise
• Precision-balanced for smooth, vibration-free braking performance
• Non-directional machined braking surface for quick and even pad bedding
• Corrosion-resistant coating on non-braking surfaces for long-term durability
• Direct OEM-style fitment — no modifications required
• Manufacturer Part Number: 623-03049L

The R1 Concepts RNC Series is an ideal upgrade for drivers seeking better braking feel and longevity compared to standard OEM rotors, whether for daily driving or performance street use.
