Not to hijack, but I think the steelies might look good...especially on a late 2nd gen (dang, I need to learn PhotoShop)... 18 X 7.5" w/ 5 x 120 bolt pattern
Personally, I think it will look horrible. The design doesn't flow well with 2nd Gens and 20's are simply too big on these cars. The 18" steelies on the Camaro posted above might have potential though.
