R1 Concepts 613-20006L RNC Series Slotted Brake Rotor with Black Zinc Coating

The R1 Concepts 613-20006L is a Series 613 RNC slotted brake rotor featuring a black zinc coating, sold individually as the left/driver-side replacement rotor. Designed for passenger vehicles and light-duty trucks, this rotor delivers consistent, reliable stopping performance for everyday driving and demanding conditions alike.

Key Features:

• Slotted Rotor Design — Precision-machined slots help evacuate heat, gases, and brake dust from the pad-to-rotor contact surface, reducing the risk of pad glazing and maintaining consistent bite
• Black Zinc Coating — Protective black zinc finish resists corrosion on the hat, hub face, and vane structure, improving rotor longevity and appearance behind the wheel
• Series 613 Construction — Premium-grade casting meets or exceeds OEM dimensional standards for a direct-fit installation with no modifications required
• Driver-Side (Left) Application — Sold as a single rotor; the "L" suffix designates left/driver-side fitment
• Double Disc Ground Braking Surface — Promotes faster and more uniform brake pad bed-in for quieter, smoother stopping from the first use

The 613-20006L is part of R1 Concepts' RNC (slotted) rotor lineup, engineered to provide a measurable upgrade over standard OEM replacement rotors in heat management and pad life. Compatible with a wide range of applications — confirm fitment using your vehicle's year, make, model, and brake position prior to installation.
