Just to add to your confusion, American Racing also makes a version called the Silverstone.
http://americanracing.com/wheels/wheels.asp?section=VThey are offering them through their custom shop. This allows you to specify backspacing on any of the sizes they offered. I seem to recall they were around $250 each, which is a decent price and were availble in a variety of widths from 7 to 12 inches in 15" diameters. Team 3 wheels are around $375 in 15 and 17" diameters, and the real Minilites can be more than that depending on how you spec them out. The real Minilites offer an off the shelf package of trans am replica wheels in 15x8, but they can do custom three piece moduler set up in a variety if widths and diameters in either aluminum or magnesium if you really want to drop some $$.
I think Panasport is also offering a similar wheel as well, but I don't recall what info I had on them.
