R1 Concepts 623-54186R RNC Series Drilled Brake Rotor

The R1 Concepts 623-54186R RNC Series Drilled Brake Rotor is a premium replacement rotor engineered for improved stopping performance and thermal efficiency. Drilled holes across the rotor face help dissipate heat and gases generated during braking, reducing brake fade and maintaining consistent pedal feel under demanding driving conditions.

R1 Concepts manufactures this rotor from high-carbon gray iron, providing greater rigidity and vibration dampening compared to standard iron rotors. Each rotor is precision-machined to strict tolerances for a direct OE-style fit and smooth, quiet operation right out of the box.

Key Features:

• Drilled rotor design for enhanced heat and gas dissipation
• High-carbon gray iron construction for strength and reduced vibration
• Precision-machined to OE specifications for direct-fit installation
• Corrosion-resistant coating on non-friction surfaces to resist rust and extend rotor life
• Balanced and tested for minimal runout and smooth braking performance
• Direct replacement — no modifications required

R1 Concepts rotors are designed to be paired with R1 Concepts brake pads for optimal system performance, though they are fully compatible with quality OE-grade pads as well. This rotor is an ideal upgrade or replacement for drivers seeking reliable, fade-resistant braking.
