R1 Concepts 623-58016R RNC Series Drilled Brake Rotor

The R1 Concepts 623-58016R RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver consistent stopping power and improved thermal management over stock brake components. R1 Concepts' RNC (Replacement No-Coat) rotors are manufactured from premium G3000 grey iron castings, meeting or exceeding OEM specifications for a direct-fit installation.

The drilled hole pattern across the rotor face serves a dual purpose: it promotes rapid heat dissipation to reduce brake fade during repeated stops, and it helps expel gases, dust, and debris from the rotor-to-pad contact surface for cleaner, more consistent braking performance. The rotor arrives with a corrosion-inhibiting coating on the non-swept surfaces (hat and vanes) to resist rust and extend service life.

Key Features:

• Drilled rotor design for improved heat dissipation and reduced brake fade
• Cast from G3000 grey iron for strength and durability meeting OEM standards
• Corrosion-resistant coating on hat and non-friction surfaces
• Direct OEM replacement — no modifications required for installation
• Balanced and tested for smooth, vibration-free performance
• Manufactured to strict dimensional tolerances for proper pad contact and wear
