It'll be low but probably doable... I used to run 15" superleggaras on mine.
I've a set of brand spandly 15x7 MOs still in the boxes that I was going to run on mine as they'll go over brembos... ET20 so fill out the arches a little more.
£300odd should see you a 2nd hand set of wheels, but you'll probably find you'll not have much in the way of tyre life in them!
