Product Details

The R1 Concepts 623-48034L is a RNC Series drilled brake rotor designed as a direct-fit replacement for factory brake systems. R1 Concepts manufactures this rotor using G3000 grade cast iron, the same material specification used in OEM rotors, ensuring consistent thermal performance and long service life.

The precision-drilled holes serve a dual purpose: they provide a path for heat, gas, and debris to escape from the rotor surface, helping to reduce brake fade during repeated or hard stops. The cross-drilled pattern also contributes to a cleaner rotor face by preventing glazing of the brake pad surface.

Key Features:

  • Drilled rotor design for improved heat dissipation and reduced brake fade
  • G3000 grade cast iron construction for OEM-level durability
  • Precision CNC-machined for accurate rotor thickness variation (RTV) and lateral runout (LRO)
  • Corrosion-resistant coating on non-swept surfaces to minimize rust and surface oxidation
  • Direct bolt-on replacement — no modifications required
  • Left-side (driver side) fitment as indicated by the "L" suffix in the part number
  • Balanced and tested to meet or exceed OEM specifications

The R1 Concepts RNC Series is engineered for drivers seeking an upgrade over plain OEM rotors while maintaining a street-friendly, daily-driver performance profile. This rotor is a left-hand (driver side) unit and is designed to work with a wide range of OEM and aftermarket brake pads.

Great delivery very time

Great pricing!

Very easy process

Really painless transaction. My item arrived essentially on time (a slight delay from the estimated delivery date - but THM was all over it, touching base with updates before I even had to reach out). My order arrived in working order and packaged well. I will definitely order from them again!

Super fast and easy! Just like I like my car.
