Thanks William,
I had actually considered the 9" rims,  Actually the 17" X 9" are much 
cheaper, but I'm a little concerned about the tire width on the 9" rims. 
I don't want them to be squeezed too far. The Mustang GTs use the 17X9 
and it looks fine with these tires. I'll have to recalculate the offset 
to make sure but I've been leaning toward the 9" wide wheels,.
