R1 Concepts 623-76056L RNC Series Drilled Brake Rotor

The R1 Concepts 623-76056L RNC Series Drilled Brake Rotor is a precision-engineered performance disc brake rotor designed to deliver improved stopping power and thermal management over a standard OEM replacement rotor. Engineered as a direct-fit, single (left-side) rotor, it is built to meet or exceed original equipment specifications while offering the added benefits of R1 Concepts' performance rotor technology.

Key Features:

• Cross-Drilled Design: Precision drilled holes reduce rotor heat buildup, helping to dissipate thermal energy during heavy or repeated braking and reducing the risk of brake fade
• Silver Zinc Plating: Corrosion-resistant zinc coating protects the rotor hub, hat, and vane structure from rust and oxidation, extending service life and maintaining a clean appearance
• Direct OEM Replacement Fitment: Engineered as a direct-fit replacement with no modifications required for a straightforward installation
• Vented Construction: Internal vane design promotes airflow through the rotor for continuous cooling during normal and performance driving conditions
• High-Carbon Iron Casting: Provides strength, durability, and consistent braking feel across a wide range of temperatures
• Single Rotor (Left Side): Sold individually; designed for left-side axle position

The R1 Concepts RNC series is part of R1's commitment to delivering aftermarket brake components that combine performance upgrades with everyday reliability. This rotor is compatible with standard brake pads and requires a standard bed-in procedure upon installation to ensure optimal pad transfer and braking performance.
