it doesn't prove, beyond a shadow of a doubt, that the wheels are in fact made of it. that's one reason i posted the last link about them possibly being made of ALON. However, using the sintering process described and throwing in massive amounts of cash the possiblity of making a set of 4 wheels is not out of the question. That's why I said i believe that those wheels are a proof of concept....if that's the case that 350Z is probably owned by someone who was directly involved in the project.
however, it is also possible that they are made out of lexan....along with a numerous number of other possible materials. The only reason I am led to believe it's alumina is because of hearsay from several engineering message boards. One of them linked to a site with small sized blocks for sale, which I've been trying to find but can't. All I remember is that they were horrendously expensive. If anyone here can find them I'd appreciate it.
