Good morning to all,
I have a 1969 Chevy Nova body and years ago I found that arching the leaf spring 2" gave the body 4" of lift. This measurement also worked well on a friends 1969 Z/28 Stocker. Using a 4 1/2" to 5" back spaced wheel (rear) on a Camaro was a favorable offset. You might still have to "roll" the lip on the inside of the rear wheelwell , You didn't specify whether or not you're using a 8" wide or 10" rim. The 10" rim spreads the side walls of the slicks out some. While fitting this arrangement into your wheelwell check that the tire doesn't hit the forward part of the leaf spring also. This worked back in the 80's when we were first building theses cars and had to use "stock length" shackles.
Just more stuff to check, I hope this helps. Over the years the " 9 x 30 " slicks we use have grown some in size. Therefore fitting them where they belong has become a slightly larger challenge. The Camaro body has been an easier body to fit tires under then the Nova body. Its possible the back is too low or you'er trying to make the ride height to low, helping to exasperate the problem. There should be plenty of Camaro racers on this forum that can point you in the right direction.
Good luck and I hope some of this helps, have a Good Day.
P.S. this was done on stock leaf springs not aftermarket springs, Multiy and Mono leaf springs at the time.
