Based on the picture you posted above it looks like your new specs will be 22x9.5 et +8.5 front and 22x10.5 et +8. I don't run 22", but sounds more aggressive than the typical 22" for our cars. Will look great if you don't end up rubbing.
Ask all the 22" guys on the forum to post op their specs, find a set you like and copy the offset.
