EBC RK Series brake rotors are engineered with an iron compound that exceeds the quality of most original material blends to reduce heat buildup, brake noise, vibration, and wear. A higher percentage of carbon and silicon leads to the formation of graphite during the curing process. The presence of graphite makes the rotor denser and softer. RK Series brake rotor kit by EBC is anodized for corrosion resistance, and rotors should be fully ready for performance driving after a 500 mile break-in period. When the company engineers who created pads that can survive 1,800-degree temperature test runs, turn their attention to brake rotors, the result is equally impressive. If installed at the same time as a new set of EBC long-life brake pads, it’s not uncommon for these rotors to last the length of the first set with more than enough life to be used with a second set. All EBC brake rotors are cast to a high metal strength rating of 150 Newton-meters and are precision CNC machined to be within tolerances of less than 0.05 millimeters. RK Series Premium OE Replacement Rotor Kit is the result of relentless testing and refinement.
