R1 Concepts 623-52011R RNC Series Drilled Brake Rotor

The R1 Concepts 623-52011R is a RNC (Round Nose Crescent) Series drilled brake rotor engineered to deliver improved stopping performance over standard OEM rotors. Featuring a precision-drilled pattern across the rotor face, this disc promotes efficient heat dissipation, reduces brake fade, and helps clear gas, dust, and debris from the rotor surface during braking.

Manufactured from premium G3000-grade cast iron, this rotor meets or exceeds OEM specifications for a direct, no-modification-required fit. Each rotor is finished with a zinc dichromate coating on non-contact surfaces to resist corrosion and maintain a clean appearance.

Key Features:

• RNC Series drilled rotor design for enhanced heat dissipation and fade resistance
• Precision CNC-machined for accurate dimensions and smooth surface finish
• G3000-grade cast iron construction for durability and consistent performance
• Zinc dichromate anti-rust coating on non-braking surfaces
• Direct OEM replacement — no modifications required for installation
• Balanced and computer-tested to minimize vibration and noise

R1 Concepts rotors are dynamically balanced and undergo strict quality control testing before leaving the factory, ensuring a quiet, vibration-free driving experience straight out of the box. This rotor is an excellent upgrade for daily drivers seeking better braking performance and a sportier appearance.
