R1 Concepts 623-47038R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-47038R RNC Series Cross-Drilled Brake Rotor is a precision-engineered replacement disc brake rotor designed to deliver enhanced stopping power over standard OEM rotors. Manufactured to strict OEM dimensional specifications, this rotor installs without modification for a direct-fit replacement.

The cross-drilled hole pattern is the defining feature of the RNC series, promoting improved airflow across the rotor face to dissipate heat more efficiently during repeated or hard braking events. Drilling also helps evacuate water, gas, and debris from the pad-to-rotor contact surface, maintaining consistent bite in wet or demanding conditions.

Key Features:

• Cross-Drilled Design: Precision-drilled holes enhance ventilation and heat dissipation, reducing brake fade under sustained use
• G3000 Grade Cast Iron Construction: High-quality iron alloy delivers consistent friction performance and long service life
• Zinc Plating / Protective Coating: Corrosion-resistant finish protects the hub, hat, and vane areas from rust and premature deterioration
• OEM-Matched Dimensions: Engineered to factory specifications for a direct bolt-on fit with no modifications required
• Vented Rotor Design: Internal venting promotes continuous airflow through the rotor body for improved thermal management
• Balanced and Tested: Each rotor is inspected for runout and balance to ensure smooth, vibration-free braking performance

The R1 Concepts 623-47038R is sold as a single rotor. It is compatible with standard OEM brake calipers and brake pads, making it an easy upgrade or replacement for worn or warped factory rotors.
