Product Details

The R1 Concepts 623-46045L is a drilled disc brake rotor designed as a direct OE-style replacement with enhanced performance characteristics. Part of R1 Concepts' RNC (Replacement Natural Carbon) series, this rotor is engineered for drivers seeking improved braking performance over a standard solid replacement rotor without sacrificing everyday driveability.

The drilled pattern across the rotor face serves multiple purposes: it aids in heat dissipation during repeated braking cycles, helps outgas brake pad gases that can cause fade, and reduces overall unsprung weight. The rotor is designed to mate with OE-spec hubs and calipers for a straightforward, no-modification installation.

Key Features:

  • Drilled rotor design for improved heat dissipation and fade reduction
  • Left/driver-side fitment — sold as a single rotor
  • OE-equivalent dimensions for direct bolt-on installation
  • High-carbon iron construction for durability and consistent bite
  • Zinc-washed hat and edges to resist corrosion during storage and break-in
  • Balanced and tested for vibration-free performance
  • Compatible with OEM and most aftermarket brake pads

The R1 Concepts 623-46045L is sold individually and is intended for the left (driver) side of the vehicle. For optimal braking balance and safety, it is strongly recommended to replace brake rotors in axle pairs.

great pricing and super fast shipping! ill continue to shop here!

part arrived on time and intact. Easy peasy.

This company is super fast to get you your order! I ordered online and figured it would be at least a couple days or so until my order would even get processed. I think they overnighted it to me! The package showed up undamaged and sealed. Unfortunately, I may have to return the product as I am thinking I would like the spikes shorter but that is no fault of Thmotorsports. Hopefully their customer service is as superior as their ordering and shipping. At this point I would definitely shop there again and recommend them.

The website was easy to navigate and your facility was the only one that had the product.

Incredibly easy to find the part and price is great.

Quick easy lookup and checkout
