R1 Concepts 623-47001L RNC Series Drilled Brake Rotor

The R1 Concepts 623-47001L is a drilled brake rotor from R1 Concepts' RNC series, engineered to deliver reliable stopping performance with improved heat management over a standard OEM replacement rotor. Built to OEM specifications, this direct-fit rotor requires no modifications for installation.

Key Features:

• Cross-Drilled Pattern: Precision-drilled holes are countersunk and chamfered to reduce heat buildup by up to 105°F, prevent cracking, and allow gases and heat to escape efficiently during hard braking
• G3000 Grade Cast Iron Construction: Manufactured from G3000 iron for excellent durability, consistent braking performance, and long service life
• Zinc Plating Coating: Applied to the hub and vane structure to provide corrosion protection, extending rotor lifespan and maintaining appearance
• OEM Direct-Fit Design: Manufactured to original equipment specifications — no modifications or adapters required for installation
• Left/Driver Side Specific: Designed specifically for the left (driver) side application, as indicated by the "L" suffix in the part number
• Vented Construction: Internal venting promotes continuous airflow to dissipate heat and reduce brake fade during repeated stops

The R1 Concepts 623-47001L is an ideal upgrade for drivers seeking improved thermal performance and corrosion resistance over a standard blank rotor, while maintaining a straightforward, bolt-on installation. A proper brake bed-in procedure is recommended after installation to ensure even pad transfer and optimal braking performance.
