R1 Concepts 613-76037R RNC Slotted Disc Brake Rotor

The R1 Concepts 613-76037R RNC Brake Rotor is a slotted performance disc brake rotor engineered to deliver reliable, consistent stopping power as a direct OE-specification replacement. Built from G3000 grade cast iron, this rotor provides excellent thermal stability and durability under a wide range of driving conditions.

Key Features:

• Diamond Slot Technology: Exclusive slotted pattern increases brake pad bite, channels away heat and debris, prevents pad glazing, and extends the service life of both the pad and rotor
• Slotted Wear Indicator: Diamond-tipped slot ends serve as a visual wear indicator — when the tips disappear, it's time for rotor replacement
• G3000 Cast Iron Construction: Premium iron grade delivers superior strength, consistent braking performance, and long-lasting durability
• Zinc Plated Coating: Full rotor zinc plating protects against corrosion on the hub and vane structure, improving appearance and longevity
• OE Specifications: Manufactured to original equipment dimensions for a direct-fit installation with no modifications required
• Double Disc Ground: Precision surface finish promotes faster, more even brake pad bed-in for quieter and smoother stops

The RNC series is ideal for drivers seeking a meaningful performance upgrade over standard blank rotors while maintaining street-friendly drivability. As with all R1 Concepts rotors, a proper break-in (bed-in) procedure is recommended upon installation to achieve optimal braking performance and pad transfer layer. Sold as a single rotor.
