FRONT EBC GD Sport Discs 321mm 5 Stud Discs for Astra G/H with 321mm VXR Brake Upgrade
EBC's wide groove discs are designed to pull cool air under the pad surface and between the disc to help both pad and disc cooling. EBC's "Blind Drilled" dimples help break down surface gasses but do not promote cracking, which has been known to occur, especially on fast road and track day use with conventional "Through Drilled" discs.
As well as aiding cooling, the grooves in the disc surface also allow dirt, dust, gasses, debris and grit to escape from between the disc and pad surface, especially under heavy braking. The grooves and dimples also keep the pad surface de-glazed throughout its useful life.
EBC sport discs are also coated to help prevent corrosion in areas which are not swept by the pad to help them stay looking better for longer. Optimum brake performance is reached once the coating is removed from the pad contact area, which when used with EBC ceramic pads and the special brake in coating on their surface will often occur in as little as 50 miles.
