ok, been offered calipers n discs n hoses off a fiesta st150

the calipers i know to be the same as the st170 focus, and i assume the discs are too

now i know iv seen s2's with these fitted upfront before, so what im after is a bit of info as to what brackets or fittings i need to get the calipers to fit etc etc

i have 17" wheels, so its not a problem. im assuming the fiesta st150 uses the same 300mm discs as the focus st170. if not, i wil just get st170 300mm discs anyways

any info appreciated
