R1 Concepts 613-47009L RNC Series Slotted Brake Rotor

The R1 Concepts 613-47009L RNC Series Slotted Brake Rotor is a performance-engineered replacement brake rotor designed to deliver consistent, reliable stopping power. Precision-machined from high-quality cast iron, this rotor features a slotted surface pattern that continuously sweeps debris, gases, and heat away from the brake pad contact surface — helping to maintain fade-free braking performance under a wide range of driving conditions.

The slotted design bites into brake pads on every rotation, keeping pad surfaces fresh and reducing glazing for more responsive pedal feel. This makes the RNC rotor an excellent upgrade for drivers seeking improved braking performance over a standard OE-replacement rotor without the added brake dust and noise sometimes associated with cross-drilled designs.

Key Features:

• Slotted rotor surface for continuous debris and gas evacuation
• Precision CNC machining for strict dimensional tolerances and proper fitment
• High-quality cast iron construction for durability and heat dissipation
• Anti-corrosion coating on non-friction surfaces to resist rust
• Balanced and tested to minimize vibration and pedal pulsation
• Direct OE-style replacement — no modifications required for installation
• Left-side (driver side) application

R1 Concepts is a California-based brake component manufacturer specializing in performance rotors, pads, and brake kits.
