Product Details

The R1 Concepts 623-46065L is a precision-engineered drilled brake rotor from the RNC (R1 Concepts) Series, designed as a direct OEM-style replacement with enhanced performance characteristics. This left-side rotor features a drilled pattern that improves heat dissipation and helps reduce brake fade during demanding driving conditions.

Key Features:

  • Drilled Venting Pattern: Cross-drilled holes allow heat, gas, and water to escape quickly, maintaining consistent braking performance
  • OEM-Quality Fitment: Engineered to meet or exceed original equipment specifications for a direct bolt-on installation
  • Premium Metallurgy: Manufactured from high-grade G3000 cast iron for excellent durability and long service life
  • Corrosion-Resistant Coating: Features a zinc or e-coating finish on non-braking surfaces to prevent rust and improve appearance
  • Balanced and Tested: Each rotor is precision balanced to minimize vibration and pedal pulsation
  • Left-Side Application: Specifically designed for the driver-side (left) wheel position — sold individually

R1 Concepts brake rotors are a popular upgrade for drivers seeking improved stopping power and rotor longevity over standard OEM replacements. The RNC drilled rotor is an excellent choice for daily drivers and performance-oriented vehicles alike.

everything fine but took longer than expected

'Ordered lug nuts for my new wheels-shipping was fast and the price was good. Everything arrived as expected and worked well. Smooth overall experience.'

Prior to purchasing I made an inquiry and recieved no response.

Good

I ordered tires. Straight forward, easy, and affordable. How ordering tires should be.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

No issues

Quick ship. Thanx

Really painless transaction. My item arrived essentially on time (a slight delay from the estimated delivery date - but THM was all over it, touching base with updates before I even had to reach out). My order arrived in working order and packaged well. I will definitely order from them again!
