mk3 mondeo calipers do fit but theres no advantage to them unless you dont want to pay the st170 tax but then there are fewer aftermarket pads made aswell so thats the down side.

there are companies that do big brake kits for the st170 like willwood and hi-spec so have a look at them but there prob over a grand new.

i did the st170 conversion on the front of my 2l first week after christmas and i'm very pleased.

didnt see much point in doing the rears as i already have rear disks and the calipers are the same and considering i can lock the rears on track theres no need for me.




PS. if you need to ask any q's about doing the fronts then send me a pm, i'll gladly help. oh and just so you know now the hub nuts need torquing to 316NM which is FT and you may need to buy a new torque wrench.
