Re: 17" supersports on a gtv
The offset for the GTV is about 30mm and for the 147 is 40mm. You'd need to space the front as well as the rear, with a TS you might get away with it but on a V6 you have the big calipers to clear too.
You could fit hubcentric spacers 10mm on the front and 15mm on the rear, plus you'd need longer wheel bolts. I ran 15mm spacers on my 156 Selespeed for 4 years without any problem (needed them to clear the Brembos I had fitted)
