R1 Concepts 613-72003L RNC Series Slotted Brake Rotor

The R1 Concepts 613-72003L RNC Series Slotted Brake Rotor is a precision-engineered replacement brake rotor designed to deliver consistent, fade-resistant stopping power. Manufactured from high-grade gray iron, this rotor features machined slots that continuously sweep the brake pad surface to clear heat, gas, and debris — maintaining a clean contact patch and improving bite throughout the rotor's service life.

Key Features:

• Slotted Design: Precision-machined slots degas the pad surface and evacuate heat buildup under hard braking, reducing brake fade
• High-Grade Gray Iron Construction: Provides excellent thermal capacity and long-lasting durability for everyday and performance driving
• Direct-Fit Replacement: Engineered to OEM specifications for straightforward installation with no modifications required
• Left Side (Driver Side) Application: Part number suffix "L" designates this as the left/driver-side rotor
• Corrosion-Resistant Finish: Coated hat and edges help resist rust and corrosion during storage and service
• Balanced and Tested: Each rotor is computer-balanced and tested for runout compliance to ensure smooth, vibration-free braking

The R1 Concepts RNC series is built for drivers who want an upgrade over a standard blank rotor without moving into a full performance package. The slotted surface provides improved wet-weather performance and consistent pedal feel, making it an ideal choice for daily drivers and light performance applications.
