R1 Concepts 623-03044R RNC Series Drilled Brake Rotor

The R1 Concepts 623-03044R RNC Series Drilled Brake Rotor is a direct-fit performance replacement rotor engineered to deliver improved stopping power and thermal management over standard OEM rotors. Manufactured from premium G3000 grade cast iron, this rotor provides the durability and consistent bite serious drivers demand.

The precision-drilled hole pattern reduces overall rotor weight, improves heat dissipation, and helps clear brake dust and gases from the rotor surface — keeping your brake pads in cleaner contact for more responsive pedal feel. Each rotor is precision-balanced and features a corrosion-resistant coating on the non-contact surfaces to resist rust and extend service life.

Key Features:

• Drilled hole pattern for enhanced heat dissipation and reduced brake fade
• G3000 grade cast iron construction for strength and long wear life
• Corrosion-resistant coating on hat and non-swept areas
• Precision-balanced for smooth, vibration-free braking
• Direct OEM replacement — no modifications required
• Manufactured to strict dimensional tolerances for proper fitment

R1 Concepts rotors are designed and tested to meet or exceed OEM performance standards, making this a reliable upgrade for daily drivers and performance-oriented vehicles alike. Always replace brake rotors in axle pairs and inspect brake pads for wear during installation.
