i've just put my original 5 spokes back on, and put a set of 17x8 et 40 in the shed as i thought they were sticking out too much. The rears were just ok, but the fronts did stick out a couple of mm. I also had the 215/45/17 tyre combo stretched look. When i took these wheels off i had to jack up the car some more to put the old 5 spokers back on, so the rolling radius was defo out. The car seems to pull a lot better now as well, so i think the gearing was out too The worst bit was after i had washed the car, it was dirty the next day due to the extra spray.
