Dimond racing wheels are crap. If your going to do widened steelies do them the right way.
If you get a set of vw steelies then their shouldn't be an issue with them mounting up, you're not changing the bolt pattern. The only issue i see is not figuring out your ETs correctly. I can't find a pic of the guy whose ETs are all jacked up, but it looks aweful. This guy did it right though
