R1 Concepts 623-58012R RNC Series Drilled Brake Rotor

The R1 Concepts 623-58012R RNC Series Drilled Brake Rotor is a high-performance direct-fit replacement rotor engineered to deliver improved stopping power and thermal management over standard OEM rotors. Precision-drilled holes across the rotor face promote rapid heat dissipation, helping to reduce brake fade under demanding driving conditions while keeping brake dust and gas buildup to a minimum.

Key Features:

• Drilled rotor design – Cross-drilled holes improve heat venting and help evacuate gas and debris from the rotor surface for consistent, fade-resistant braking
• OEM-quality fitment – Manufactured to OEM specifications for a direct bolt-on installation with no modifications required
• High-carbon gray iron construction – Provides excellent thermal conductivity and durability for long service life
• Precision balanced – CNC-machined for tight tolerances, minimizing vibration and pedal pulsation
• Corrosion-resistant coating – Non-friction surfaces feature a protective coating to resist rust and surface oxidation during storage and daily use
• Right-side rotor – Designed specifically for the right (passenger) side application

R1 Concepts rotors undergo rigorous quality control and are tested to meet or exceed OEM performance standards. The RNC Series is an excellent upgrade for daily drivers seeking reliable, high-performance braking without sacrificing streetability or pad compatibility.
