R1 Concepts 623-47015R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-47015R is a RNC Series cross-drilled disc brake rotor engineered to deliver reliable stopping performance and improved thermal management over stock rotors. R1 Concepts designs this rotor as a direct-fit replacement, maintaining OEM mounting dimensions for straightforward installation.

The cross-drilled hole pattern is the defining feature of the RNC Series, allowing heat, gas, and moisture to escape from the braking surface during hard stops. This helps reduce brake fade and keeps rotor temperatures in check under demanding driving conditions. The rotor is finished with a silver zinc coating on the non-braking surfaces to protect against rust and corrosion, extending the rotor's appearance and service life.

Key Features:

• Cross-drilled hole pattern for improved heat dissipation and reduced brake fade
• Silver zinc corrosion-resistant coating on hub and vane surfaces
• Direct OEM replacement fitment — no modifications required
• Manufactured to meet or exceed original equipment specifications
• Balanced and precision-machined for smooth, vibration-free operation

R1 Concepts manufactures this rotor to function with a wide range of OEM and aftermarket brake pad compounds. The zinc coating on the braking surface will wear away during the initial break-in period, which is normal and expected. Following the R1 Concepts recommended break-in procedure will ensure optimal pad transfer and long rotor life.
