They will fit.
In my experience, ET38
might touch the insides of the front arches, but if you drop to ET35 they
might touch the outside edges of the rear arches. No real better answer than that, but ET38 will be fine. At worst you might need some 3-5mm Spacers if they do touch the front inner arches.
Go 205/40/17 for the tyres for defo.
