R1 Concepts 623-21045R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-21045R is a precision-engineered drilled disc brake rotor from the RNC (Race-N-Cruise) Series, designed to deliver reliable stopping power for street and performance driving applications. Manufactured from high-carbon gray iron, this rotor offers superior heat absorption and dissipation compared to standard OE-style rotors.

The cross-drilled pattern reduces rotor surface temperature by venting heat away from the braking surface, helping to minimize brake fade during repeated or aggressive stops. The drilled holes also allow gases and debris produced during braking to escape, promoting more consistent pad-to-rotor contact and extending overall brake life.

Key Features:

• Cross-Drilled Design — Improves heat dissipation and reduces brake fade under demanding conditions
• High-Carbon Gray Iron Construction — Provides excellent thermal capacity, strength, and durability
• Corrosion-Resistant Coating — Non-braking surfaces feature a protective coating to resist rust and maintain appearance
• Precision Balanced — Computer-balanced to minimize vibration and pedal pulsation
• Direct-Fit Replacement — Engineered as a direct OE replacement for hassle-free installation
• R1 Concepts RNC Series — Designed for drivers seeking a performance upgrade over standard rotors

The 623-21045R meets or exceeds OEM specifications and is ready to install straight out of the box. It is an ideal upgrade for drivers who want improved braking performance and thermal management without a full race-spec setup.
