R1 Concepts 623-54240R RNC Cross-Drilled Brake Rotor - Black Zinc Coated

The R1 Concepts 623-54240R is a cross-drilled disc brake rotor finished in a corrosion-resistant black zinc coating. Part of R1 Concepts' drilled rotor lineup, this rotor is engineered as a direct-fit replacement designed to improve braking performance over a standard blank OEM-style rotor while delivering an aggressive appearance behind the wheel.

The cross-drilled holes serve a dual purpose: they provide a pathway for heat, gas, and debris to escape from the braking surface, helping to reduce brake fade during repeated or hard stops. The black zinc coating protects the hub, hat, and vane structure from rust and corrosion, extending the service life and maintaining a clean look over time. Note that the coating will wear from the pad contact surface during the initial break-in process — this is normal and expected.

Key Features:

• Cross-Drilled Design – Promotes heat dissipation and gas venting to reduce brake fade
• Black Zinc Coating – Corrosion-resistant finish protects non-friction surfaces for longer rotor life
• Direct-Fit Replacement – Engineered to OEM mounting specifications with no modifications required
• Double Disc Ground Braking Surface – Promotes faster, more even brake pad bed-in and smoother stopping
• Right Side (Passenger Side) – Sold as a single rotor; verify position before ordering

R1 Concepts recommends following a proper break-in (bed-in) procedure after installation to ensure even pad transfer and optimal braking performance. Always replace brake pads when installing new rotors for best results.
