The Subzero is by far the most difficult and requires the most machine work to be done. Therefore increasing it's cost. The wheel is 7.5" wide, fyi, and requires a +48 offset.
I was in Vegas for the SEMA show last week and on the way back towing a car blew out my truck's tranny. So now I'm stuck in the desert waiting to get it fixed.
I'll attempt to catch up when I get back.
Thanks, Rishie
