R1 Concepts 613-03050L RNC Series Slotted Brake Rotor

The R1 Concepts 613-03050L RNC Series Slotted Brake Rotor is a performance-grade replacement rotor engineered for drivers who demand reliable, consistent stopping power. Featuring precision-cut slots across the rotor face, this rotor is designed to continuously sweep the brake pad surface clean of gases, debris, and heat buildup — maintaining optimal bite and fade resistance under a wide range of driving conditions.

R1 Concepts manufactures this rotor using high-quality gray iron castings that meet or exceed OEM specifications, ensuring a precise fit and confident performance. The slotted design improves wet-weather braking response and extends overall pad life by promoting even wear across the friction surface.

Key Features:

• Slotted rotor design — evacuates heat, gases, and debris from the pad/rotor interface for consistent braking performance
• High-quality gray iron construction — meets or exceeds OEM standards for durability and thermal stability
• Precision machined — tight tolerances minimize runout and vibration for smooth, quiet braking
• Direct OEM replacement — bolt-on fitment with no modifications required
• Protective coating — non-friction surfaces treated to resist corrosion during storage and initial use
• MPN: 613-03050L — left-side (driver side) application

The R1 Concepts RNC Series is an excellent choice for daily drivers and performance enthusiasts looking to upgrade from stock rotors without sacrificing streetability. This rotor installs with standard hand tools and is ready to use straight out of the box.
