Rotors, EBC, 2009-11 STS, GD Sport, Front, 12.4"

EBC Brakes now produces all of its GD series with a long lasting corrosion resistant finish. The coating is either thermic or for less popular smaller batch items a NITROTHERM™ process of anti corrosive paint is applied using this revolutionary process that coats with warm Nitrogen producing a better finish. EBC uses the strictest quality controls, specifications and a 100% run out and dimensional check, plus all USA sport rotors are slotted at the Las Vegas facility of the USA operation using the latest CNC controls and tooling for superb accuracy. On a global scale most EBC rotors are made from high quality G3000 iron composite castings and 100% of these are precision machined in either the UK or the USA. The dimple drilled rotor was invented by EBC back in the 90’s and has been imitated by many because of its ability to offer pad degassing without “Through Drilling” disc or rotor holes which has been shown to promote rotor cracks. The wide aperture slots on the EBC units actually draw cool air under the brake pad and rotor interface and help cool the temperatures of the pad contact which can shoot up to well over 1000 degrees at the very heart of the brake pad during heavy braking and can cause brake fade or loss of brake effect. These “Full sweep” slots on the EBC Sport Brake rotor also help remove dirt dust debris and water from the braking area but without doubt the main benefit of such sport rotors is their ability to maintain a flat and parallel pad surface throughout the lifetime of the brake pad set.
