Product Details

The R1 Concepts 623-46038L is a RNC Series cross-drilled brake rotor designed as a direct-fit, performance-upgrade replacement for the factory rotor. This is the left-side (driver's side) rotor, engineered to deliver confident stopping power for daily driving and light performance use.

R1 Concepts' RNC Series rotors are manufactured from G3000 grade cast iron for consistent thermal stability and long service life. The precision cross-drilled holes reduce heat buildup, improve wet-weather braking performance, and help expel brake gas and debris from the rotor surface. A zinc plated finish provides corrosion resistance during storage and on non-braking surfaces.

Key Features:

  • RNC Series Cross-Drilled Design – Precision-drilled holes enhance ventilation and heat dissipation for consistent braking performance
  • G3000 Grade Cast Iron Construction – High-quality iron alloy for strength, durability, and fade resistance
  • Zinc Plated Corrosion Protection – Protects hub and vane surfaces from rust and corrosion
  • Direct OEM Replacement Fit – Built to OEM specifications; no modifications or adaptors required
  • Left Side (Driver's Side) – Sold as a single rotor for the left/driver's side position
  • Vented Rotor Design – Internal vane structure promotes airflow and thermal management

The R1 Concepts 623-46038L is an excellent choice for drivers looking to upgrade from worn factory rotors with a performance-oriented drilled rotor at an accessible price point. For best results, brake pads should always be replaced at the same time as rotors.

Low friction purchase. Fast shipping. Very satisfied.

Great prices and great selection

Your system showed delivery three days before it was delivered. Caused of concern.

Everything was smooth and easy

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.

Had the tires I wanted at a fair price and delivered quickly! Thank you!

Hope I get my order thanks you

It would have been better if you listed the dimensions so hopefully it fits

good
