R1 Concepts 623-46038R RNC Series Drilled Brake Rotor

The R1 Concepts 623-46038R RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver confident stopping power and improved thermal management. Constructed from high-carbon gray iron, this rotor provides excellent heat dissipation and resistance to warping under repeated braking cycles.

The drilled hole pattern reduces rotor weight and promotes airflow across the rotor face, helping to keep brake temperatures in check during everyday driving and spirited use. The rotor's vented design further enhances cooling by channeling air through the interior of the rotor body.

Key Features:

• High-carbon gray iron construction for superior strength and durability
• Drilled hole pattern for reduced weight and enhanced heat dissipation
• Vented rotor design promotes internal airflow to minimize brake fade
• Precision machined to OEM-spec tolerances for direct bolt-on fitment
• Corrosion-resistant coating on non-friction surfaces helps prevent rust during storage and initial use
• Balanced and tested to minimize vibration and brake pedal pulsation

R1 Concepts rotors are manufactured to meet or exceed OEM specifications, making the 623-46038R a reliable upgrade or direct replacement for worn factory brake rotors. Each rotor undergoes strict quality control checks to ensure consistent performance and a smooth, quiet braking experience.
