R1 Concepts 613-40011L RNC Slotted Brake Rotor

The R1 Concepts 613-40011L RNC Series Slotted Brake Rotor is a performance-engineered replacement brake rotor designed to deliver consistent, reliable stopping power. Manufactured using high-quality cast iron, this rotor features a precision-machined slotted surface that continuously sweeps debris, gases, and heat away from the brake pad contact area, maintaining optimal braking performance under a wide range of driving conditions.

Key Features:

• Slotted Surface Design: Machined slots channel away heat, gases, and brake dust to improve pad bite and reduce fade
• Precision Balanced: Computer-balanced construction minimizes vibration and pedal pulsation for a smooth braking feel
• High-Quality Cast Iron: Durable iron alloy construction provides long service life and consistent thermal performance
• Direct-Fit Replacement: Engineered as a direct OEM replacement for easy, straightforward installation
• Corrosion-Resistant Coating: Zinc or e-coating finish on non-friction surfaces helps resist rust and corrosion during storage and service
• Left Side (Driver Side) Application: This is the left-side (L suffix) rotor

The R1 Concepts RNC Series is designed for drivers seeking an upgrade over standard OEM rotors without sacrificing daily driveability. The slotted design is especially well-suited for those who demand improved brake responsiveness, whether in everyday commuting or performance driving applications. R1 Concepts part number 613-40011L is a direct replacement rotor — always verify fitment with your vehicle's year, make, and model before installation.
