Product Details

The R1 Concepts 623-47037L is a RNC Series drilled brake rotor engineered for improved stopping performance and thermal management. Designed as a direct-fit replacement, this rotor installs without modification for a straightforward upgrade from your factory brake hardware.

R1 Concepts' drilled rotors feature a precision-machined drilling pattern that helps evacuate heat, gas, and debris from the rotor surface during braking, maintaining consistent pad contact and reducing fade under repeated braking cycles. The rotor is manufactured from high-carbon gray iron for durability and long service life.

Key Features:

  • Drilled rotor design for enhanced heat dissipation and fade resistance
  • High-carbon gray iron construction for strength and longevity
  • Precision CNC-machined for strict dimensional accuracy and OE fitment
  • Corrosion-resistant coating on non-friction surfaces to resist rust and improve appearance
  • Direct OE replacement — no modifications required for installation
  • Balances and tested for smooth, vibration-free operation

The R1 Concepts 623-47037L RNC drilled rotor is an excellent choice for drivers seeking an upgrade over standard smooth rotors while maintaining reliable, street-ready braking performance.
