i used the wide track set up originally and after a few months it chew up the bearing casings on the inner cvs of the shafts
the strut tops are about an inch an half narrower then the mk3 golf, plus on the vr6 they have the wide track which is an inch longer and then when u use the steering rack the wheels will toe in abit even when fully wound in
as for the hubs the vr6 hubs are angled different for the bottom ball joint so u cant just bolt them to the ibiza wishbones and the vr6 ball joints wont fit the ibiza wishbones either
in the end i just used ibiza cupra shafts,wishbones,rack,uprated arb and hubs with vr6 drive flanges pressed in and re-drilled g60 discs
hope that helps
