your best bet is just use the brake disc, calipers and brackets as they will fit the std hubs but might need to some spacers on the bolts for the carrier.
as for the hubs fitting the driveshafts on you car i dont think they would as your running either ib5 or mtx75 gearbox and st170 runs getrac 6spd.
to get yours to run abs will need the abs pump and module will need looms sensors etc so not really worth doing as will cost a fortune to get fitted and for the parts.

the st170 disc are 300mm,have a set on my mrk2 mondeo 2.0 16v with mrk3 mondy calipers also run abs too the power they generate can throw you through the front screen need them a few times when people have pulled out on me
