lol there are plenty of wide rims you can get if you know where to look

try looking over vipstylecars.com they got lots of crazy sets there like what peachy mentioned of 19x10 19x12
i've seen sets being sold of 18x12, 18x13 as well with -7 and -15 offsets.
im just not sure how a full widebody would look but if done right it should go crazyyyyyy
keep your car black, but if you are really planning on getting it painted, have your car blasted with pearl and maybe a colored flakes. i've seen black with some pink and gold flakes and the paint job looks wicked in the sun!
