If lowering is in your future, and want an 8.5" wide wheel, look for something with an offset between 45mm and 48mm. Also, a good set of coiliovers will be necessary to dial in the right amount of drop.
HotRodWagon is correct in the offset numbers, but you can still run the Rotiforms. They can make whatever wheels you want in custom spec with whatever offsets you want. You can get them in 4x108 or 5x108 if you so choose as well, but their website lists the wheels at $1250 each - so unless you're flush with cash.....
