R1 Concepts 623-45007L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-45007L RNC Series Drilled Brake Rotor is a high-performance replacement rotor designed to deliver improved stopping power and heat dissipation over standard OEM rotors. Precision-drilled holes across the rotor face allow gases and heat to escape quickly during braking, reducing brake fade and extending pad life under demanding driving conditions.

Key Features:

• Drilled rotor design promotes rapid heat and gas evacuation for consistent, fade-resistant braking performance
• Left-side application — designed specifically for driver-side installation (denoted by the "L" suffix)
• High-carbon gray iron construction for superior durability, vibration damping, and thermal stability
• Precision-machined to strict OEM tolerances for direct bolt-on fitment with no modifications required
• Zinc-plated hat and edges resist corrosion and maintain a clean appearance
• Balanced and tested for smooth, vibration-free operation

R1 Concepts rotors are engineered for drivers who demand reliable performance from their brake system. The RNC series is ideal for everyday street driving that benefits from enhanced cooling and a sporty aesthetic. Sold individually.
