Make way for the replacement rotors that are like OE in dimensions but exceeds the factory specifications when it comes to thermal build-up, brake noise, vibration standards and over-all wear with its high-quality gray iron! The EBC RK Series Premium OEM Brake Rotors are all these and more! These rotors apply innovative engineering concepts to create an iron compound that is far more superior to the majority of original material blends. The graphite content that forms during the curing process which is the result of the high percentage of carbon and silicone in the blend is the secret behind the quality of the rotors. It makes the rotor softer and denser at the same time. The evenly distributed heat minimizes warping and cracks and eliminates that annoying brake squeal caused by vibrations.
