Have you checked tyre availabilty yet? 235 and 225 are usually in a 60 series.
Also, not only is the tyre height changing, but also you are loosing an inch in rim diameter don't forget.
So, my last EA had 235/60s on 14x8, instead of the 15s, and it was nearly spot on. My current car will soon get 225/60 and 235/60 as well, and I am not in the least concerned about speedo error.
235/60 sit a lot better on 8s than 7s, unless you already have your rims.
