the stock wheel is 16x7.5 +53 on 5x100. Sadly, a +38 offset will not be enough, at least not with a big wheel...you may get away with it with a 16" and small tire, but I don;t think its big enough for the spinner effect to really capture someone's attention.
And who cares if it "generally accepted" or not. If everyone did what was generally accepted the world would be BORING. YOU do whatever YOU want. Its YOUR car.
