R1 Concepts 623-01011L RNC Series Drilled Brake Rotor

The R1 Concepts 623-01011L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver consistent, fade-resistant stopping power. R1 Concepts manufactures this rotor from premium G3000 grade cast iron, meeting or exceeding OEM metallurgical standards for durability and heat management.

The drilled hole pattern reduces rotor mass for improved unsprung weight, while simultaneously promoting heat dissipation and helping to clear gas and debris from the rotor face during braking. This results in more consistent pad contact and reduced brake fade under demanding driving conditions.

Key Features:

• Drilled rotor design for enhanced cooling and gas evacuation
• Premium G3000 grade cast iron construction
• Precision machined to OEM dimensional tolerances for direct bolt-on fitment
• Zinc dichromate coating on non-friction surfaces to resist rust and corrosion
• Computer-balanced to minimize vibration and brake pedal pulsation
• Meets or exceeds FMSI/SAE and OEM specifications
• Direct OEM replacement — no modifications required

The R1 Concepts RNC Series rotor is an ideal upgrade or replacement for drivers seeking improved braking performance over a standard OEM rotor. Sold individually as a single rotor.
