R1 Concepts 623-72040R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-72040R RNC Series Drilled Brake Rotor delivers upgraded stopping performance over standard OE replacement rotors. Precision-drilled holes across the rotor face work continuously to dissipate heat and expel gases and water, helping to maintain consistent braking bite in demanding conditions.

R1 Concepts manufactures this rotor from high-grade grey iron using a precision casting process to ensure dimensional accuracy, proper balance, and long service life. A protective coating is applied to non-friction surfaces to resist corrosion and maintain a clean appearance behind the wheel.

Key Features:

• Drilled rotor design for improved heat dissipation and gas evacuation
• High-grade grey iron construction for strength and durability
• Corrosion-resistant coating on hat and outer edge surfaces
• Precision-machined friction surfaces for consistent pad contact
• Direct OE replacement fit — no modifications required
• Designed to meet or exceed OEM specifications

The 623-72040R is a direct bolt-on replacement designed for straightforward installation. It is compatible with standard OEM-style brake hardware and calipers for the applicable fitment.
