Product Details

The R1 Concepts 623-80053L RNC Series Drilled Brake Rotor is a direct-fit, performance-oriented replacement rotor engineered for reliable stopping power and long service life. Designed as a left/driver-side rotor, this unit slots seamlessly into your existing brake system without modification.

R1 Concepts' RNC rotors feature precision drilled holes across the rotor face, promoting rapid heat dissipation and helping to prevent brake fade during sustained or aggressive braking. The drilling pattern also aids in the outgassing of gases and debris from brake pad surfaces, maintaining consistent pad-to-rotor contact for confident, predictable braking performance.

Key Features:

  • Drilled rotor design for improved heat dissipation and reduced brake fade
  • Left/driver-side fitment (suffix "L" designation)
  • Direct OE replacement — no modifications required
  • Precision-machined for minimal runout and smooth, vibration-free braking
  • Zinc-plated or coated finish to resist corrosion on non-swept surfaces
  • Manufactured to meet or exceed OEM specifications
  • Balanced and tested for consistent performance

R1 Concepts is a trusted name in aftermarket brake components, producing rotors and pads engineered for both everyday driving and performance applications. The 623-80053L is an ideal upgrade or replacement for drivers seeking improved braking feel and durability over standard OEM rotors.

It was very simple to order the part I needed.

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.

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

Awesome experience! Would definitely do business with you guys again

received on time

THMotorsports had some tires in a size that I was having a hard time finding elsewhere. The price was fair, the shipping super fast, and the tires were exactly as described. Thanks THMotorsports!

Amazing prices and shipping rates
