Rear Mk4 NA wheels are 16x8, if I remember correctly the fronts are 16x7, but I could be mistaken. 16x9 rear and 16x8 front? That sounds more like it, doesn't it? Anyway, turbo Mk4 wheels are 17x9.5 rear and 17x8 front. If you can find a set, FD wheels are nice and light, not to mention pretty cheap...
