Product Details

The R1 Concepts 623-03021L RNC Series Drilled Brake Rotor is a precision-engineered performance replacement rotor designed to deliver improved braking response and thermal management over standard OE rotors. The drilled hole pattern increases airflow across the rotor face, helping to dissipate heat more efficiently during repeated braking cycles and reducing the risk of brake fade under demanding driving conditions.

Key Features:

  • Drilled hole pattern promotes heat dissipation and reduces brake fade
  • Helps clear water, dust, and debris from the rotor surface for consistent pad contact
  • Manufactured from high-carbon gray iron for superior durability and noise reduction
  • Precision-balanced to minimize vibration and pedal pulsation
  • Electrostatic coating on non-friction surfaces helps resist corrosion during storage and initial use
  • Direct OE replacement — no modifications required for installation
  • Left (driver) side fitment — sold individually

R1 Concepts rotors are G3000-grade castings that meet or exceed OEM specifications, making the RNC 623-03021L a reliable upgrade for drivers seeking improved braking performance without sacrificing everyday drivability.

Ordering was easy, received item in a reasonable amount of time. Well packaged.

I sent in a return request haven't heard anything back would like to return this item

Quick delivery easy to use site

Ordered Enkei brand hubcentric rings, company sends Coyote brand hubcentric rings. Will they work, yes but it's a classic bait-n-switch sales tactic. Wish THMotorsports was upfront & honest with their customers.

Fast shipping
