R1 Concepts 613-45045L RNC Slotted Brake Rotor Left Side

The R1 Concepts 613-45045L RNC Slotted Brake Rotor is a precision-engineered, performance-grade disc brake rotor designed to deliver confident, consistent stopping power. Part of R1 Concepts' RNC series, this slotted rotor is designed as a direct OEM-style replacement with a performance upgrade, offering improved heat dissipation and pad bite over standard smooth rotors.

Key Features:

• Slotted Design: Directional slots channel heat, gas, and debris away from the braking surface, reducing brake fade and extending pad life
• Slot-Only Construction: Retains the structural integrity of a solid rotor face while still improving braking performance over blank rotors
• Zinc Plated Coating: Corrosion-resistant zinc coating protects the non-braking surfaces of the rotor, including the hat, hub, and vanes, helping maintain appearance and longevity
• Left-Side Application: Designed specifically for the left (driver's side) position — sold as a single rotor
• OEM-Grade Casting: Manufactured to OEM dimensions and specifications for a direct, no-modification fit
• Vented Construction: Internal vane venting promotes airflow through the rotor for continuous cooling during heavy braking

The R1 Concepts RNC series is an ideal upgrade for drivers seeking better braking performance without the additional maintenance concerns associated with cross-drilled rotors. A proper bed-in procedure is recommended after installation to fully seat the brake pads to the rotor surface and achieve optimal braking performance.
