R1 Concepts 623-63127R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-63127R RNC Series Drilled Brake Rotor delivers reliable, consistent stopping power in a direct OE-replacement form factor. Engineered to meet or exceed original equipment specifications, this rotor is precision-machined from high-quality G3000 gray iron casting for superior heat dissipation and long service life.

The drilled hole pattern reduces unsprung rotational weight, helps evacuate heat, gas, and brake dust from the rotor surface, and provides improved bite and pedal feel — especially during repeated or demanding braking events. The internal vane design promotes airflow between the rotor faces for additional cooling.

Key Features:

• Drilled hole pattern for improved heat and gas evacuation
• G3000 gray iron casting for durability and consistent performance
• Precision-machined for accurate fitment and minimal runout
• Zinc dichromate coating helps prevent corrosion during storage and initial use
• Direct OE replacement — no modifications required for installation
• Manufactured to strict dimensional tolerances for proper pad contact and wear

R1 Concepts rotors are balanced and tested to ensure smooth, vibration-free operation. The RNC (Replacement No-Coat) designation indicates a performance-grade replacement rotor built for everyday driving and spirited use alike. Manufacturer Part Number: 623-63127R.
