R1 Concepts 613-42031L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-42031L RNC Series Slotted Brake Rotor is a direct-fit, performance-oriented replacement rotor designed to deliver reliable stopping power with improved heat dissipation. The slotted rotor face channels away brake dust, gas, and water from the pad surface, maintaining consistent bite and reducing fade during demanding driving conditions.

Key Features:

• Slotted Rotor Design: Precision-machined slots sweep debris and gases away from the brake pad contact surface for consistent, fade-resistant braking
• Left/Driver Side Fitment: Purpose-built as a direct replacement for the front or rear left-side rotor position (verify with vehicle fitment)
• OE-Quality Construction: Cast from high-grade iron to meet or exceed original equipment specifications for thickness, balance, and runout tolerances
• Corrosion-Resistant Finish: Protective coating on the hat and non-contact surfaces helps resist rust and extend rotor appearance between service intervals
• Balanced for Smooth Operation: Computer-balanced to minimize vibration and brake pedal pulsation during everyday and performance use
• Bolt-On Installation: Engineered for direct OE replacement with no modifications required

R1 Concepts is a trusted manufacturer of brake components for automotive, truck, and performance applications. The RNC line offers a cost-effective upgrade over plain OE rotors, making it an ideal choice for drivers looking to improve braking response and longevity without a full big-brake kit investment.
