Why did you create a second thread asking the same questions???
VMR's are available in limited offsets. If you want help with an offset choice please take the time to inform us of the the choices.
FYI it's not a good idea to switch tires 2x's per year on the same wheels. It ends up being more cost effective to have two sets of wheels. Frequent tire swaps deteriorate the tire sidewalls. Plus do the math... switching tires is $100 - $150 x (2) each year. I would keep your OEM wheels (which are far higher quality than VMR's) and buy a second set of wheels for winter. You can then sell them when you are done with them. Or buy a used set of wheels from a forum member.
