Would you do it to an Opel GT or a 57 Chevy?
It would be a crime.
Those rimes that came with it belong.
Remember you are driving a cool car many steps ahead of any car today.
Remember on back to the futere they had to put some whitr walls on that DMC?
It just didn't look right.
I would have to back Madeline up on this one as well. Of course this is just my opinion but I don't think wire wheels belong on a Z. As for the width I was told that 8" stick out a little so I would imagine that 9 would be in the roller skates park.
