R1 Concepts 613-40113R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40113R RNC Series Slotted Brake Rotor is engineered for drivers who demand consistent, high-performance stopping power on the street and track. R1 Concepts' RNC (Race-N-Street) rotors are precision-machined from premium G3000 grey iron casting, delivering excellent thermal stability and long-lasting durability under repeated heavy braking.

The slotted rotor design continuously sweeps debris, brake dust, and gases away from the pad surface, maintaining a clean contact patch for improved bite and fade resistance. This makes the 613-40113R an ideal upgrade over OEM rotors for performance-oriented driving applications.

Key Features:

• Slotted rotor design for improved gas and debris evacuation
• G3000 grey iron casting for superior strength and heat dissipation
• Precision-machined for minimal runout and smooth, vibration-free braking
• Corrosion-resistant coating on non-friction surfaces to prevent rust and extend service life
• Direct OEM replacement — no modifications required for installation
• Meets or exceeds OEM specifications for fit, form, and function
• Manufactured to strict quality control standards

The R1 Concepts 613-40113R is a direct-fit replacement rotor designed to restore and enhance braking performance. Whether upgrading from worn OEM rotors or looking for a more performance-focused alternative, this RNC slotted rotor delivers reliable stopping power and improved pedal feel.
