Product Details

The R1 Concepts 623-13033L is a front left drilled brake rotor from the RNC Black Series — R1 Concepts' eLINE Black line engineered to deliver upgraded stopping performance at an accessible price point. Featuring a precision-drilled face pattern, this rotor improves heat dissipation, reduces brake fade, and promotes cleaner pad contact for consistent, confident braking.

Key Features:

  • Precision Cross-Drilled Holes: Countersunk drill pattern maximizes heat escape and ventilation while reducing the risk of cracking under thermal stress
  • Black Series Finish: Black zinc coating on the hat and vane structure provides corrosion resistance and a sharp, aggressive appearance behind the wheel
  • G3000 Grade Cast Iron Construction: OEM-spec metallurgy delivers strength, durability, and smooth, even pad contact
  • Direct-Fit Replacement: Engineered to OEM dimensions for bolt-on installation with no modifications required
  • Front Left (Driver Side) Application: Sold as a single rotor — position-specific fitment
  • Vented Design: Internal vane structure promotes continuous airflow to keep rotor temperatures in check during repeated braking

The R1 Concepts RNC Black Series is an ideal upgrade for drivers seeking improved thermal management and a more aggressive rotor aesthetic compared to standard OEM replacements. Always replace brake pads when installing new rotors and follow a proper bed-in procedure for optimal performance and longevity.

You guys got me the part very fast. Thanks

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Well-designed website and search, prices and checkout experience was nice.

Shipping was fast and efficient! Very happy that the fuel pump I ordered was available and arrived in perfect condition. This was a quality fuel pump that was difficult to find and was very pleased with the procurement of my order. I will use THMotorsports again! Thank you.

Great experience, Thank you

Quick and easy!
