Update to my wheel debacle...
I ordered two silverstone wheels from VTO. 15x6 with a -19mm offset. While the backspace was correct, the necked down area of the barrel contacted with the brake caliper. I now have $400 worth of paperweight...
I then looked into the 15" LAT 70 wheel that VTO sells. It's a 15x7 with a -20mm offset. I conferred with Dale who told me that the minilite that he specs out is the same dimension. I stopped by Sunbeam Specialties (who sells the polished version of the same wheel from VTO), and they were kind enough to let me borrow one wheel for a fit check. It fits, but just barely. The balance weights need to go on the land immediately adjacent the back side of the face. I pickled up a full set of wheels from SS and mounted 205/50-15 Falken RT660's for the front and 225/45-15 for the rear. For whatever reason, that tire is a Tirerack.com only tire - my local tire shop could not get them.
I was able to mount the fronts but in heavy rain I gave up on the rears. I'll get pictures at some point and post them.
Cheers, -Kevin
