It seems like all the affordable wheels out there are like +50-60 offset
I was even looking at 9x12's for vettes (since my bolt pattern is 120) and still they were huge offset..so they need more than an inch added or more than an inch spacer.
It looks to me to get the right wheels you'll be spending as much as you would be on oems :S could be wrong but I'm definitely having trouble finding wheels
If you add to the lip won't you be making the offset more negative? And you said the offset is good to begin with.
I'd hate to cut my arms apart >_<
