I had 15x7 ET35 on my EK4 and they were sitting pretty flush with the fenders. When I lowered the car with H&R springs and used 205/50/15 Federal RS-R (these are pretty wide for 205s) they were rubbing. Didn't run much camber though.
I think that with wider rims and lower offset than mine and if you are thinking of lowering the car you would have to consider an appropriate wheel size and I'm almost sure you'd have to modify your fenders and maybe increase the camber so there would be no rubbing.
Dunno if this helps though
