R1 Concepts 613-45015L RNC Series Slotted Brake Rotor

The R1 Concepts 613-45015L is a RNC Series slotted brake rotor engineered for improved braking performance and extended rotor life. Manufactured from high-grade G3000 cast iron, this rotor delivers consistent stopping power while resisting the heat buildup and brake fade associated with demanding driving conditions.

The slotted surface design continuously cleans and deglazes brake pad material with every application, ensuring a fresh contact surface and optimal bite. Slots also help evacuate heat, gas, and debris from the rotor face, maintaining strong, consistent braking performance over time.

Key Features:

• Slotted rotor design for improved heat dissipation and pad deglazing
• G3000 high-carbon cast iron construction for durability and thermal stability
• Precision-machined for minimal runout and smooth, vibration-free braking
• Corrosion-resistant coating on non-friction surfaces to prevent rust and extend shelf life
• Direct OE replacement fit — no modifications required
• Left-side (driver's side) fitment as indicated by the -L suffix
• Balanced and tested to OEM standards for quiet, reliable operation

The R1 Concepts 613-45015L is a direct-fit replacement rotor designed for easy installation. Whether upgrading from a standard smooth rotor or replacing a worn OEM unit, this slotted rotor offers a performance-forward solution backed by R1 Concepts' manufacturing standards.
