Those rims are cool, think for the info on them.
Just an FYI, I think the bolt pattern is 4.5" or 114.3mmor something like that and I think the newer cars like the 300 are like 115mm or so. I mention this because I think that it was mentioned that of over torqued there would be stress on the studs or something. I like the idea of using those rims because you might be able to dig up a cheap set from a local salvage yard or something. Looks cool.
