EBC brakes now produces all of its GD series discs with a new, long lasting corrosion resistant finish. The coating is either the world famous thermic or for less popular smaller batch items we use the new NITROTHERM process of anti corrosive paint applied using this revolutionary process that coats with warm Nitrogen producing a better finish. One point to consider before making your choice of sport rotor is the air noise that can be noticed with sport rotors. With all slotted rotors there will be an increase in air noise as the rotor passes beneath the pads under normal driving and braking. Some people like this kind of "Turbo" sound and others do not.
EBC manufacture the vast majority of its automotive rotors including Premium brake rotors in the UK or Europe. Outside these sources where castings or finished rotors have to be bought in to complement the range, the strictest quality controls are applied to ensure the safety and quality of the parts we sell. We source only highest quality parts from well known and proven OEM manufacturer vendors and we are responsible for and guarantee those parts to fit and perform as expected. All suppliers of castings for the EBC group are ISO approved to the highest specification and have been visited and approved by the German TUV authorities.
