Product Details

The R1 Concepts 623-46041L is a drilled disc brake rotor from R1 Concepts' RNC Series, engineered as a direct-fit replacement that delivers improved thermal performance over a standard smooth rotor. This is a single left-side (driver-side) rotor designed for a precise OEM-style fitment with no modifications required.

The cross-drilled holes serve a dual purpose: they allow heat, gas, and moisture to escape from the rotor surface during braking, helping to reduce brake fade and maintain consistent stopping power. The drilled pattern also contributes to a reduction in unsprung rotational weight compared to a fully solid disc.

Key Features:

  • Drilled rotor design for improved heat and gas dissipation during repeated braking
  • Direct OEM replacement fit — no drilling, cutting, or modification needed
  • Left/driver-side single rotor (sold individually)
  • Corrosion-resistant coating on non-contact surfaces to resist rust and extend service life
  • Precision machined to strict dimensional tolerances for smooth, vibration-free operation
  • Compatible with OEM and aftermarket brake pads

R1 Concepts rotors are manufactured to meet or exceed OEM specifications and are a popular upgrade for drivers seeking improved braking feel and rotor longevity over standard replacement parts. The RNC Series is well-suited for daily driving applications where reliability and consistent performance are the priority.

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.

Great deal, great service.

Decent shipping time, package was loosely packed however. Would do business again.

EASY AND QUICK CHECKOUT. GREAT PRICES. FAST DELIVERY.

It was a quick easy decision to purchase my new stainless steel prop through their site. Good job.
