R1 Concepts 613-40008R RNC Slotted Brake Rotor with Black Zinc Coating

The R1 Concepts 613-40008R RNC Brake Rotor is a premium slotted disc brake rotor engineered to deliver consistent, reliable stopping performance for passenger vehicles and light trucks. Part of R1 Concepts' RNC (Slotted Only) Series, this rotor features a black zinc coating and precision machining for a direct OE-replacement fit with no modifications required.

Key Features:

• Slotted Design: Machined slots increase brake pad bite, help evacuate heat, dust, and debris from the rotor surface, and prevent brake pad glazing for consistent pedal feel
• Built-In Wear Indicator: The slots function as a visual wear indicator — when slots are no longer visible, the rotor has reached minimum thickness and should be replaced
• Black Zinc Coating: Applied to the hub, hat, and vane areas to provide long-lasting corrosion resistance, helping maintain appearance and extend rotor service life
• Double Disc Ground: Precision surface finish promotes faster, more even brake pad bed-in for quieter and smoother initial performance
• G3000 Cast Iron Construction: Manufactured from G3000-grade iron for excellent thermal stability, durability, and OEM-comparable performance
• OE Specification: Designed as a direct-fit replacement to OEM dimensions — no cutting, drilling, or modifications required for installation
• Sold Individually: This listing is for a single rotor (1 piece)

The R1 Concepts 613-40008R is an ideal upgrade or OE replacement for drivers seeking improved braking consistency and corrosion resistance over standard smooth rotors. Always replace brake pads when installing new rotors and follow the recommended break-in procedure for optimal performance.
