guys and it seems that, on the '05 STi's, the 225/45 gives an incorrect spedometer reading......the 235/45 makes it spot on.....the S203 has 235/45's, stock....go figure.
The 225's do, and I have confirmed that it is about 3-4 mph off at 70 mph on a GPS. Maybe it was the S203 that I saw with the 235/45 size.
