Product Details

The R1 Concepts 623-48006L RNC Series Drilled Brake Rotor is a precision-engineered replacement disc brake rotor designed to deliver reliable stopping power and improved heat management over a standard OEM-style blank rotor. Built to OEM fitment specifications, this rotor installs without modification for a straightforward, direct-fit replacement.

Key Features:

  • Cross-Drilled Design: Precision-drilled holes are countersunk to reduce heat stress and prevent cracking, allowing heat and gases to escape efficiently during braking
  • G3000 Grade Cast Iron Construction: High-quality iron formulation provides excellent strength, thermal stability, and long service life
  • Silver Zinc Plated Coating: Corrosion-resistant zinc finish protects the rotor hub and vane structure from rust and premature deterioration
  • Direct OEM Replacement: Engineered to match original equipment dimensions and mounting specifications — no modifications required
  • Left Side (Driver's Side) Application: This rotor is designated for the left-side position

R1 Concepts rotors are balanced and tested to minimize vibration and pedal pulsation. For best results, always replace brake pads when installing new rotors and follow a proper bed-in procedure to seat the pads evenly across the rotor surface.

The price was great and delivery out standing. Much greater than I ever expected. Great job.

Thanks!

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.

Shipping too expensive!

Fast, fast, fast. No issues. No worries.

Easy

Super smooth transaction, and fast delivery. Just waiting for my mechanic to open packages and verify all correct parts, but I don't expect any issues. Would definitely purchase and recommend others do business with Motorsport.com again
