My buddy was looking at putting some of these on his Ford.

He's looking at the 8 lug though so his cost would be about $300 shipped.

I much prefer a rim with more offset so that you get a deeper dish - as opposed to a stock rim with spacers. The Proton has about 30K miles on it with the aftermarket rims (see my gallery). So far, no mechanical problems due to increased offset.

Warning tho. If you add spacers, you'll have to trim your cladding and pound out your fender wells. The spacers will cause your tires to rub.
