Premium Series vs. E-Line Series

The Premium series uses high carbon which results in a stronger rotor that can handle more demanding driving styles and conditions. In addition, the Premium Series rotors uses a black electro-coating process that gives the rotor a two-tone color finish which will also help protect against rust. The Premium Series also have center split castings while the E-lines series do not.

The E-Line Series uses an iron grade of G3000 which is great for those who do not need the additional stopping power. E-Line Series rotors come with a silver zinc plating through out the rotor and is not two-toned in color.
