R1 Concepts 613-91002L RNC Slotted Disc Brake Rotor

The R1 Concepts 613-91002L RNC Slotted Brake Rotor is a performance-grade disc brake rotor engineered for drivers seeking improved stopping power over a standard blank rotor. Featuring R1 Concepts' slotted rotor design, this rotor channels heat, brake dust, and debris away from the pad contact surface for more consistent, fade-resistant braking performance.

Key Features:

• Diamond Slot Technology: Exclusive slotted pattern increases brake pad bite, expels heat and debris, prevents pad glazing, and extends pad and rotor service life
• Wear Indicator: Diamond-tipped slot ends serve as a built-in rotor replacement indicator — when the tips wear away, it's time to replace
• G3000 Grade Cast Iron Construction: Manufactured from G3000 iron grade for excellent stability, durability, and consistent braking performance
• Zinc Plated Finish: Protective zinc coating applied to the hub and vane areas guards against corrosion and extends overall rotor lifespan
• Double Disc Ground Surface: Promotes faster, more even brake pad bed-in for quieter and smoother initial stopping performance
• OE Specifications: Manufactured to original equipment dimensions for a direct-fit, no-modification installation

The R1 Concepts RNC rotor is well-suited for daily driving, street performance, light towing, and hauling applications. As with all new rotors, a proper break-in (bed-in) procedure is recommended upon installation to ensure optimal pad-to-rotor contact and maximum braking efficiency.
