Product Details

The R1 Concepts 623-72052L is a precision-engineered drilled disc brake rotor from R1 Concepts' RNC (R1 Natural Coating) Series, designed as a direct-fit replacement for the left side of the vehicle. This rotor delivers a measurable upgrade over standard OEM rotors, combining enhanced stopping power with improved thermal management.

Key Features:

  • Cross-Drilled Design: Precision-drilled holes are countersunk to reduce heat stress and prevent cracking, allowing heat to escape efficiently and lower rotor operating temperature
  • Direct-Fit Replacement: Engineered to OEM specifications for a straightforward, no-modification installation
  • R1 Natural Coating (RNC): Protective coating applied to non-braking surfaces to resist corrosion, extend rotor life, and maintain appearance
  • Vented Construction: Internal vane design promotes continuous airflow through the rotor to dissipate heat during heavy braking
  • Left-Side Application: Part number suffix "L" designates this as a driver-side or left-position rotor
  • OEM-Compatible Dimensions: Manufactured to match original equipment tolerances for proper fitment and pad compatibility

R1 Concepts rotors are manufactured to strict quality standards and are ideal for drivers seeking a performance-oriented replacement rotor with improved heat dissipation over solid OEM units. Always replace brake pads when installing new rotors and follow a proper bed-in procedure for optimal performance and longevity.

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

I was pretty happy with the service. I ordered the part on a Sunday afternoon and paid $9.99 for 2 day delivery and it arrived on Friday 5 days later so not sure I got what I paid for in that regard.

I'm always amazed at what a great job the hull cleaner does and it's soooo easy!

Sp far so good thanks
