What i would do is get onto Tuning developments on here they are doing a break package consisting of Brake Fluid, EBC Discs and Yellow stuff pads for about 260euro i think. would defo be your best bet, i never found the Mintex pads any good to be honest
thicker discs as used on celica caliper upgrades will not crack. its the tiny 19mm thickness of disc that cant take the heat of hard driving.
o and brakes are spelt this way, even the moderators cant spell these days!
