R1 Concepts 613-31104L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-31104L is a RNC Series slotted brake rotor designed as a direct OEM replacement with enhanced stopping performance. Precision-machined from high-grade G3000 cast iron, this rotor delivers consistent, fade-resistant braking for daily drivers and performance-minded enthusiasts alike.

Key Features:

• Slotted Design: Precision-cut slots channel heat, gas, and debris away from the rotor face to maintain consistent pad contact and reduce brake fade
• G3000 Cast Iron Construction: High-carbon, balanced metallurgy provides excellent thermal stability, reduced vibration, and extended rotor life
• Direct OEM Replacement: Engineered to match factory specifications for a straightforward, no-modification installation
• Drilled and Slotted Variant: Slots improve wet-weather braking performance by displacing water from the rotor surface
• Left/Driver Side Fitment: This unit (suffix "L") is specifically designed for the left (driver) side application
• Corrosion-Resistant Finish: Protective coating on non-contact surfaces helps resist rust and extend shelf life prior to installation
• Balanced and Precision Tested: Each rotor is tested for runout and balance to ensure smooth, vibration-free braking

The R1 Concepts RNC Series brake rotor is an ideal upgrade for drivers seeking improved braking performance over a standard smooth rotor without the cost of a full big-brake kit. This rotor is sold individually and is intended for the left/driver side position.
