R1 Concepts 623-47042R RNC Drilled Disc Brake Rotor with Black Zinc Coating

The R1 Concepts 623-47042R RNC Drilled Brake Rotor is a precision-engineered performance disc brake rotor featuring a cross-drilled design and a durable black zinc protective coating. Engineered as a direct-fit replacement, this rotor installs without modification and is designed to deliver improved stopping performance over standard OEM rotors.

The drilled hole pattern promotes efficient heat dissipation by allowing hot gases and debris to escape from the rotor surface during braking. This helps reduce brake fade and keeps rotor temperatures in check under demanding driving conditions. The black zinc coating provides corrosion resistance across the hat and non-swept surfaces, maintaining appearance and extending service life.

Key Features:

• Cross-Drilled Design — Precision-drilled holes aid in heat dissipation and help prevent brake fade during repeated or aggressive braking
• Black Zinc Coating — Corrosion-resistant finish on the hub and non-contact surfaces for long-lasting protection and clean appearance
• Direct-Fit Replacement — Engineered to OEM specifications for straightforward installation with no modifications required
• Balanced Performance — Designed for street and performance driving applications demanding reliable, consistent stopping power
• Quality Construction — Manufactured to meet or exceed OEM dimensional and metallurgical standards

As with all new performance rotors, a proper brake bed-in procedure is recommended after installation to transfer an even layer of brake pad material onto the rotor surface and achieve optimal braking performance. Always replace brake pads when installing new rotors.
