I have a Z06 and a grey Turbo T... and I'm always wondering the same thing...what the Buick would look like if I threw the vette's wheels on the Buick. Probably the bad thing is going to be seeing how small the buick's rotors really are...Next week I have to throw new tires on the front of the Z06, so while the wheels are off, I can throw them on one side of the Buick and take a pic...I doubt 265 40 17's with the Z06 wheel's back spacing would work up front without rubbing as my stock buick T wheels with 235 60 15's rub sometimes turning hard.
