Product Details

The R1 Concepts 623-54229L is a drilled disc brake rotor from R1 Concepts' RNC Series, designed as a direct-fit replacement for the driver-side (left) position. Precision-engineered from high-quality cast iron, this rotor delivers improved stopping performance over a standard OEM-style rotor while maintaining a clean, straightforward appearance.

Key Features:

  • Cross-Drilled Design: Precision-drilled holes promote heat dissipation, reduce brake fade, and help channel away gas and dust buildup during heavy or repeated braking
  • Countersunk Drill Holes: Holes are countersunk to minimize stress concentration and reduce the risk of cracking under thermal cycling
  • Direct-Fit Replacement: Engineered to match OEM mounting dimensions for a no-modification, bolt-on installation
  • Zinc Plating: Protective zinc coating on non-braking surfaces guards against rust and corrosion, extending rotor life and maintaining appearance
  • Driver-Side (Left) Position: This rotor is specifically designed for the left/driver-side application — MPN suffix "L" designates position
  • Balanced Performance: Suitable for everyday street driving with enhanced heat management compared to standard blank rotors

The R1 Concepts RNC Series drilled brake rotor is a reliable upgrade for drivers seeking improved thermal performance and a more aggressive look without the added wear characteristics of a slotted surface. Always replace brake pads when installing new rotors and follow a proper bed-in procedure to maximize performance and longevity.

Happy with order

Ordering was easy and product delivered on time

Shipping took longer than expected as I paid for expedited shipping. I reached out to ask why it wasn't sent two day and got no reply. The customer service could really use improvement and this is reflected in multiple reviews. However, the products arrived safely and as described. I'm very satisfied with the pricing as well. At the end of the day, that's the most important thing.

Customer service was nice and kind, still waiting on my return for my second product I purchased. The first purchase was perfect.

Super grateful you had the part. I searched other location and nobody had it in stock. You saved my bacon after the freezing temps. Will definitely shop here again and very fast delivery!

Great prices and exceptional delivery, think the order was delivered before I clicked submit ;)

Fast shipping, good price, great communication. Can't ask for more.
