The Offset is going to be way different from 2004 to 2005. When the body style changed, so did a lot of other things with the car! We don't recommend the usage of a 10.5" wide wheel for 05+ cars. You may be able to get away with that wide of a rim, if you run a spacer but I'm not exactly sure what Millimeter you would need, considering we've never tried to make it fit.
