They would be in 8's and 10's for sure. Working on deep trim rings too. The center cap is the only issue with keeping the stock look. You can expand the wheel to 20" but cant really expand the cap much and keep lug nuts exposed like the truck rallys. IMO, if you wanted to expand the cap and cover the lug nuts you might as well buy the vette rallys with the derby caps. I will work on finalizing a pic and getting it up in a few days. This is something I'm doing in my spare time so I have to keep my full time employer somewhat happy.
