R1 Concepts 623-13035R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-13035R RNC Series Drilled Brake Rotor is a precision-engineered replacement disc rotor designed to deliver confident, reliable stopping power for street and performance driving applications. Built to OEM fit specifications, this rotor installs without modification for a direct, hassle-free replacement.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote airflow and heat dissipation across the rotor face, reducing brake fade during demanding stops
• G3000 Grade Cast Iron Construction: High-quality base material ensures consistent performance, durability, and resistance to thermal cracking
• Zinc Plated Coating: Corrosion-resistant finish protects the hub, vanes, and non-contact surfaces from rust, extending rotor life and improving appearance
• OEM-Spec Dimensions: Engineered to factory specifications for direct fitment — no drilling, cutting, or modification required
• Vented Construction: Internal vane design maximizes thermal management and keeps operating temperatures in check under repeated heavy braking
• Countersunk Drill Holes: Strategically placed and countersunk to prevent stress cracking and maintain structural integrity over the rotor's service life

R1 Concepts RNC Series rotors are an excellent upgrade or like-for-like replacement for drivers seeking improved thermal performance and a cleaner aesthetic over standard blank rotors. A proper break-in (bed-in) procedure is recommended after installation to ensure optimal pad transfer film and braking consistency.
