Product Details

The R1 Concepts 623-21044L RNC Series Drilled Brake Rotor is a precision-engineered performance disc brake rotor designed to deliver superior stopping power over standard OEM replacements. Built to direct-fit specifications, this left-side rotor installs without modification and is an ideal upgrade for drivers seeking improved thermal performance and braking consistency.

Key Features:

  • Precision Cross-Drilled Design: Drilled holes are countersunk to maximize heat dissipation, reduce operating temperatures, and help prevent rotor cracking under repeated braking stress
  • G3000 Grade Cast Iron Construction: High-quality cast iron formula delivers the strength and durability needed for consistent, long-lasting braking performance
  • Silver Zinc Plated Coating: Protective zinc finish guards against corrosion and rust, extending rotor life and maintaining appearance
  • Direct-Fit Replacement: Engineered to OEM specifications for a hassle-free, no-modification installation
  • Improved Ventilation: Drilled holes promote airflow across the rotor face, reducing brake fade during demanding driving conditions
  • Left Side (Driver Side) Application: This single rotor is designated for the left/driver-side position

The R1 Concepts RNC Series rotor is an excellent choice for daily driving, light performance use, and general street applications where upgraded thermal management and corrosion resistance are priorities. For best results, replace brake pads simultaneously and follow the manufacturer's recommended bed-in procedure after installation.

Easy shopping and easy ordering

The turbo (s475sx-e) has been my best purchase this year. The order was placed at the end of the workday and Thmotorsports shipped it the very next morning, also the box arrived in magnificent condition, the turbo was picture perfect without a blemish. Thmotorsports was the most affordable out of all ten sites that were considered, with top notch shipping. I have to say Thmotorsports was the best choice for my genuine part.

I received my items in a very timely manner.

I found the product I wanted, and the order was easy to complete. All info was clear and precise, so did not have to speak with anyone! Acknowledgement of the order was prompt and was filled and shipped almost immediately. Packaged well and received within a few days. I certainly will consider the seller should the time arise in the future.
