R1 Concepts 623-72052R RNC Series Drilled Brake Rotor

The R1 Concepts 623-72052R RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver reliable stopping power and consistent performance. Manufactured from high-quality G3000 gray iron, this rotor meets or exceeds OEM specifications while offering the added benefits of R1 Concepts' sport-oriented rotor technology.

Key Features:

• Drilled Design: Precision cross-drilled holes improve heat dissipation, reduce brake fade, and help expel gas and debris from the rotor surface for consistent braking performance
• G3000 Grade Cast Iron: Premium gray iron construction provides excellent thermal stability, durability, and long service life
• OEM-Quality Fitment: Engineered to match original equipment dimensions for a direct bolt-on installation with no modifications required
• Zinc Dichromate Coating: Non-braking surfaces are coated to resist corrosion and maintain a clean, finished appearance
• Computer Balancing: Each rotor is computer balanced to minimize vibration and ensure smooth, quiet braking
• Vented Construction: Internal vane venting promotes airflow through the rotor for continuous cooling during heavy braking

The R1 Concepts RNC (Replacement Non-Coated) series is ideal for drivers seeking a quality drilled rotor upgrade over a standard OEM replacement. Each rotor is individually inspected for dimensional accuracy and surface finish before leaving the factory, ensuring it meets strict quality standards for runout and thickness variation.
