Level car with spring shims?

[ssanto]

I've got a 1968 Camaro I'm going to be taking to the track for HPDE. In the back I've got almost 1" difference in height left-to-right. I need to put in some spring spacers to lower the car a bit already because it the rear is about an inch higher than the front.

Would it make sense to use different size lowering blocks on the left/right to try and adjust for the height differences?

These are some used springs that I got off Craigslist. Barring buying new ones, I'm just trying to get things better if possible. I've already removed the shocks and loosened all the eye bolts on the springs to releive any tension from there.


Thanks!
