George it has been quite awhile since I had the wheels made(~10-12 months give or take). When Dave and I discussed the wheels it was usually b.s. He and I did talk about offsets, but not that much and I do not remember the numbers now. I would usually would mention the b.s. and sometimes he would roughly calculate it from there. The only thing I know for sure is the b.s. is 7" and they fit exactly the way I was hoping. You could try contacting Dave and mention my wheels, he might be able to help you out on this. Gen2's Pantera in the wheels section had a very similar fit, but I believe were 12" wide. They were also American Republic Wheels(Campy Clones) but with a different style barrel. He had a b.s. of 7.25".
