R1 Concepts 613-46016L RNC Series Slotted Brake Rotor

The R1 Concepts 613-46016L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand improved stopping power and consistent brake feel. R1 Concepts' RNC (Race N Cruise) rotors are designed to deliver enhanced performance suitable for both street driving and spirited track-day use.

Slotted Design Benefits:

• Slot venting continuously sweeps brake pad gases, debris, and water away from the rotor face for a cleaner, more consistent contact surface
• Reduces brake fade under hard or repeated braking conditions
• Improves wet-weather braking performance by evacuating water from the rotor surface
• Helps deglaze brake pads over time for sustained braking efficiency

Construction & Quality:

• Manufactured from premium G3000 gray iron casting for optimal thermal conductivity and durability
• Precision-machined to OE specifications for direct, no-modification fitment
• Finished with a zinc dichromate coating on non-friction surfaces to resist rust and corrosion
• Balanced and tested for runout compliance to minimize vibration and pedal pulsation

The 613-46016L designation identifies this as the left-side (driver's side) rotor. R1 Concepts rotors are a direct OEM replacement, making installation straightforward for professional technicians and experienced DIY mechanics alike.
