That would be a serious rake angle if you don't raise the front... Hehehe.

If you don't raise it all that much, I don't think you'll notice any harsh side effects. If you near the limit of the torsion bars adjustment range though, you more than likely will - and preloading them that much isn't a good idea.

Keep it within reason and you should be just fine.
