R1 Concepts 623-42006R RNC Series Drilled Brake Rotor

The R1 Concepts 623-42006R RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered for improved stopping performance and thermal management. R1 Concepts manufactures this rotor using premium G3000 grade cast iron, delivering consistent, reliable braking in a wide range of driving conditions.

The precision drilled hole pattern serves a dual purpose: reducing overall rotor weight for improved unsprung mass and allowing heat and gas to escape quickly from the rotor surface during heavy or repeated braking. This helps reduce brake fade and keeps your brake pads biting cleanly and consistently.

Key Features:

• Drilled hole pattern for superior heat dissipation and gas venting
• G3000 premium cast iron construction for durability and consistent performance
• Precision machined to OEM fit and dimensional specifications
• Corrosion-resistant coating on non-braking surfaces to resist rust during storage and installation
• Computer-balanced to minimize vibration and pedal pulsation
• Direct bolt-on replacement — no modifications required

R1 Concepts rotors are manufactured to meet or exceed OEM standards, making the 623-42006R a reliable upgrade over worn or standard factory rotors. Ideal for daily drivers seeking an improvement in braking response and rotor longevity.
