R1 Concepts 613-46028L RNC Series Slotted Brake Rotor

The R1 Concepts 613-46028L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand consistent, fade-resistant braking. Manufactured from premium G3000 gray cast iron, this rotor delivers excellent thermal stability and long service life under a wide range of driving conditions.

The RNC Series features precision-cut straight slots across the rotor face, which continuously sweep debris, gases, and brake dust away from the pad surface. This keeps the contact patch clean and maintains consistent bite throughout the braking event. The slots also help reduce brake fade during repeated or heavy stops by promoting heat dissipation.

Key Features:

• Precision-cut straight slot pattern for consistent pad bite and debris evacuation
• Premium G3000 gray cast iron construction for excellent strength and thermal performance
• Computer-balanced design minimizes vibration and pedal pulsation
• Zinc dichromate coating on non-contact surfaces resists corrosion and rust
• Direct OE replacement — no modifications required for installation
• Manufactured to strict dimensional tolerances for precise fitment

The 613-46028L is the left-side (driver side) application of this rotor. R1 Concepts rotors are a trusted upgrade for daily drivers, commuters, and performance enthusiasts looking to improve stopping power over stock brake components.
