I;ve been looking at these for some time and here's what I have come up with. The ones we want are the 911 Turbo set, cause the spacing on the rear is very similar to ours. As for the bolt pattern, I don't know and can't seem to find anyone who knows. Haven't called porcshe yet. A friend of a friend owns a car shop here in town and sells all high end cars. He also sells the rims... M3, Benx and Porcshe. The are replicas but he said he would give them to me at little over cost, like $200 a wheel for 18's. I asked him if I could bring my truck in, put it on the lift and see if the set would work or not, and figure it out from there. I haven't had a chance to do this, but if we can get some more info, I will try and go up there within the next week and see if I can try it.
