They're offered in a variety of offsets and styles, and I don't know what they all are
my 951 phones are 16x7 and 16x8 and the offsets are either 52 or 55 mm on both sets.
I don't have them right here or I would check for you.
My plan is the same as yours, I'm going to do my brake conversion and run these wheels until I can afford something else. But I might get them polished, and if they turn out really nice I may just keep them.
