Hi there, i recently found out that my 17" alloys are et38 lol, i know that vauxhall should be et49, but the alloys were on my car when i bought it.....

is this a serious problem or not, they have been on the car for quite a while now, and i noticed that the rear drivers side tyre rubs a little about a month ago.

All arch's have been flared/rolled slightly, but should i do the rear drivers side slightly more?

Thanks, Luke
