I lowered the front of my 95 ZR-1 a few years ago. I've decided it's too low. I cut the rubber on top of the Mono leaf spring. I can't remember how much I cut off. I'm hoping some one can tell me the thickness of the factory rubber that is on a stock spring.
I happen to have the front spring out of my 91 Z07. I believe all year C4 springs interchange. Mine measures 13/64" from the top of the spring to the top of the metal cap.
Did you cut the aluminum cushion mounts under the spring when you did it? I know I had to, to take up the space of the removed rubber so the spring mounts/bolts would hold the spring in place when I did the wife's 95 LT1.
Inspect the spring, measure and compare 'heights' using the FSM dimension points. In the '95 FSM these should be near 3-21. You want to after checking the spring for condition just confirm that they're equal side to side. Front springs are different '90 & '91, then '92+ for the fabrication of the ends where it meets the LCA. If dimensions are all equal side to side I believe you could fabricate a shim to stuff into the LCA pocket to raise the car. I'm quite confident of that. I believe you can do this without removing the spring or other suspension components. You won't need 1" each side!!
I suggested this to a fellow quite some time ago and he fought it for quite a while. It did ultimately correct his 'ride height' when he did it. I don't know that he finalized his with a fabrication but he did accomplish it using some available loose parts. This is a thread that summarizes his adventure. He's a 'great guy' and I'm sure could pass on to you some of his adventure and some shortcuts maybe.
I really appreciate the information. I'll study it tonight and see what I can come up with.
Thanks Again for the help!
You can't tell until you get into actually inspecting the front spring. Using the measurements is a real benefit to diagnostics, it just works. If there's no physical damage to the spring a shim into the LCA should solve your issues. Replace the front spring? Ultimately you might need to but I'd expect LCA shim to solve your issues.
The spring is in good shape. I was just looking at my FSM about trim height. I've got lower profile tires than stock but I think I can come up with a height that will help raise it enough. I'm thinking, what you said about, the shim under the end of the spring would be the easiest way.

If you had access to a LCA to determine a correct fabrication it might be considered a large benefit. Do you have or could you 'close by' come up with a LCA to determine shape?
