R1 Concepts 613-40107L RNC Slotted Disc Brake Rotor Left/Driver Side

The R1 Concepts 613-40107L RNC Slotted Brake Rotor is a direct-fit, performance-oriented disc brake rotor engineered to deliver reliable stopping power and consistent pedal feel. Designed as a left/driver-side replacement, this rotor slots directly into factory brake system locations with no modifications required.

Key Features:

• Slotted Surface Design: Precision-machined slots increase brake pad bite, channel away heat, gas, and debris from the friction surface, and help prevent brake fade during repeated stops
• Wear Indicator Slots: The slots serve as a built-in rotor wear indicator — when slots are no longer visible, minimum rotor thickness has been reached and replacement is due
• G3000 Iron Construction: Cast from high-grade G3000 iron for superior strength, thermal stability, and long service life
• Double Disc Ground: Precision double-disc grinding promotes faster, more even brake pad bed-in and contributes to quieter, vibration-free operation
• Zinc Plating: Protective zinc coating applied to the hat, hub, and vane areas guards against rust and corrosion, extending rotor lifespan and maintaining a clean appearance
• OE-Spec Dimensions: Manufactured to original equipment specifications for a hassle-free, bolt-on installation
• Left/Driver Side Fitment: This is a single rotor intended for the left (driver) side position

R1 Concepts' RNC Series slotted brake rotors strike a balance between everyday street performance and durability, making them an excellent upgrade or replacement for worn OEM rotors. Always replace brake pads when installing new rotors and follow the recommended bed-in procedure for optimal performance.
