R1 Concepts 623-03028L RNC Series Drilled Brake Rotor

The R1 Concepts 623-03028L RNC Series Drilled Brake Rotor is a high-performance, direct-fit replacement rotor engineered for improved stopping power and thermal management. Manufactured to OEM specifications, this rotor installs without modification and restores confident, consistent braking performance.

Key Features:

• Cross-Drilled Design: Precision-drilled holes improve airflow across the rotor face, dissipating heat faster and reducing brake fade during heavy or repeated braking
• G3000 Grade Cast Iron Construction: Premium-grade cast iron provides the strength, durability, and thermal capacity needed for reliable everyday and performance use
• Silver Zinc Plating: Corrosion-resistant zinc coating protects the hub, vanes, and non-swept surfaces from rust and environmental exposure, extending rotor service life
• OEM-Compatible Fitment: Engineered to match original equipment specifications for a straightforward, hardware-compatible installation
• Vented Rotor Construction: Internal vane structure promotes continuous airflow between rotor faces, maintaining lower operating temperatures for longer pad and rotor life
• Left-Side Application: This is the driver-side (left) rotor — part number suffix "L" denotes left-hand fitment

The R1 Concepts RNC Series delivers a reliable performance upgrade over standard OEM rotors, making it an excellent choice for drivers seeking improved braking response and durability without the cost of a full big-brake kit.
