R1 Concepts 623-03049R RNC Drilled Brake Rotor

The R1 Concepts 623-03049R RNC Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver reliable stopping power with improved heat dissipation over standard solid rotors. Part of R1 Concepts' RNC (Natural Coating) series, this rotor features a zinc-based protective coating applied to non-friction surfaces to guard against rust and corrosion during storage and break-in.

Key Features:

• Drilled Design: Precision-drilled holes promote airflow across the rotor face, dissipating heat quickly and reducing brake fade during repeated stops
• Countersunk Drill Holes: Countersunk geometry helps prevent cracking at hole edges under thermal stress
• G3000 Grade Cast Iron: Manufactured from high-grade G3000 cast iron for consistent friction surface quality and long service life
• Natural Coating (RNC): Protective zinc-based finish on hat and non-friction surfaces resists corrosion and surface rust out of the box
• OEM-Style Direct Fit: Engineered to OEM specifications for bolt-on installation with no modifications required
• Vented Construction: Internal vane venting provides additional thermal management for sustained braking performance

The R1 Concepts RNC series is an ideal choice for drivers seeking an upgrade from worn OEM rotors without sacrificing daily-drive comfort. It is recommended to replace brake pads at the same time as rotors for optimal bedding and performance.
