R1 Concepts 613-39025R RNC Slotted Brake Rotor

The R1 Concepts 613-39025R RNC Slotted Brake Rotor delivers reliable, street-focused braking performance through a precisely machined slotted rotor design. Engineered to OE specifications, this rotor installs as a direct replacement with no modifications required, making it an ideal upgrade or like-for-like swap.

Key Features:

• Diamond Slot Technology: Exclusive slotted pattern increases brake pad bite, expels heat, dust, and debris from the braking surface, and helps prevent pad glazing for more consistent stopping power
• Built-In Wear Indicator: The slots double as a visual rotor wear indicator — when the slots are no longer visible, it signals that the rotor has reached minimum thickness and should be replaced
• Double Disc Ground Surface: Precision double disc grinding promotes faster, more even brake pad bed-in and contributes to quieter, smoother operation
• Black Zinc Plated Coating: Full-rotor black zinc plating protects the hub and internal vane structure from corrosion, extending service life and maintaining appearance
• G3000 Iron Construction: Cast from G3000-grade iron for the optimal balance of strength, thermal capacity, and durability demanded by OE and performance applications
• OE-Spec Fitment: Manufactured to original equipment specifications for a precise, hardware-free direct fit installation

The R1 Concepts RNC series is designed for daily drivers and street performance applications where consistent, fade-resistant braking is the priority. As with all new rotor installations, a proper brake pad bed-in procedure is recommended to achieve optimal performance and longevity.
