My car has a strange offset (+20, on 7.5" wheels i think)

Most wheels I see on craigslist, RS, ebay, have around 38-45 offsets.

Anyone know where I can find something that will look good on my car without getting spacers?

really depends on your price range.. you can get +20 in higher name brand wheels but $$$

[ilvtofu]

brand isn't important preferably less than $1000 with tires included.
something 225/45/17 or 225/40/18 will do

rota would probably be your best bet.

[ilvtofu]

where do they sell them?
