| R1 Concepts E-Line Cross-Drilled Rear Brake Rotors For 2004-07 Cadillac CTS-V SEDAN R1 Concepts E-Line Series brake rotors are a great option for those who want a medium performance upgrade over their factory (OEM) brakes. Every E-Line rotor is manufactured using G3000 grade Iron for great stability and stopping power and comes silver-zinc plated to protect against rust and maximize the lifespan of the rotor. Cross-Drilling helps prevent rotor warping and helps aid cooling by allowing hot gases to escape from the interior of the disc, compared to smooth rotors.
Applications
E-Line Series vs. Premium Series
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.
The Premium series uses high carbon iron construction, which results in a stronger rotor that can handle more demanding driving conditions than E-Line rotors. 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 feature center split castings while the E-lines series do not. |
