R1 Concepts 623-58022R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-58022R RNC Series Brake Rotor is a precision-engineered cross-drilled disc brake rotor designed to deliver improved stopping performance over stock rotors. Built to OEM specifications for a direct-fit, no-modification-required installation, this rotor is an ideal upgrade for drivers seeking enhanced braking response and thermal management.

Constructed from G3000 grade cast iron, the rotor provides the strength and heat tolerance required for consistent, fade-resistant braking. The cross-drilled hole pattern reduces rotor surface temperature by promoting airflow across the braking surface, helping to dissipate heat buildup during repeated or hard stops. Countersunk and chamfered drilling prevents stress fractures and maintains rotor integrity over the long term.

Key Features:

• G3000 grade cast iron construction for durability and thermal stability
• Cross-drilled hole pattern improves heat dissipation and reduces brake fade
• Chamfered and countersunk drilled holes prevent cracking and extend rotor life
• Silver zinc plating on non-braking surfaces protects against corrosion
• Direct OEM replacement — no modifications required for installation
• Balanced and precision-machined for smooth, vibration-free braking

The zinc-plated finish on the hat, vanes, and non-contact surfaces guards against rust and corrosion, keeping the rotor looking clean behind the wheel. This is a single rotor; confirm the quantity needed for your application before ordering.
