R1 Concepts 613-46064L RNC Series Slotted Brake Rotor

The R1 Concepts 613-46064L is a left-side slotted brake rotor from R1 Concepts' RNC (R1 Concepts Natural Cast) Series, engineered for drivers who demand consistent stopping power and improved rotor longevity over stock replacement units.

R1 Concepts slotted rotors feature precision-machined slots across the rotor face that continuously clean and deglaze brake pads during operation. This design promotes better heat dissipation, reduces brake fade under demanding driving conditions, and expels gas and debris from the braking surface for more reliable, consistent contact between rotor and pad.

Key Features:

• Slotted rotor design for improved heat evacuation and pad deglazing
• Left-side fitment (driver's side) for direct OEM-style replacement
• Manufactured to precise OEM dimensional tolerances for a proper, no-modification fit
• G3000-grade cast iron construction for durability and thermal stability
• Zinc dichromate or e-coating on non-swept surfaces to resist corrosion during storage and service
• RNC Series provides a balance of performance and everyday street usability
• Computer-balanced for smooth, vibration-free braking

The R1 Concepts 613-46064L is a direct OEM-style replacement rotor suitable for street driving and light performance use. Pairing with quality brake pads is recommended to maximize the benefits of the slotted surface design.
