instead of adding the .08 between existing .12 on your stack, add the .08 thick x .95 in diameter on top of the stock stack and then add a pair of .10 x 1.30 or a .08 + a .10(same as your largest stock shim diameter) on top. My $.02
The stacks I used as examples were just for an example. I have no idea whats in my shocks currently.
I just wanted to make sure the basic concepts I had in my head were correct.
