Thanks for the advice, i will avoid 17s, will stick with 16s or look at 15s if they will fit over the front brakes.
I have large disk conversion, so i dont think 15s will fit.
I have big brakes too, corrado g60 calipers with mk2 valver discs, are you running 280mm? Good thing about 15s with a 45 profile tyre you can get quite low without upsetting the handling by over compensating with the suspension.
