Help Lowering My Z

[zrss]

I'm lowering my '94 using Vette Brakes & Products kit which, for the front, consists of wedges that I am supposed to glue to the stock spring in place of the factory rubber pads. I have a few questions.

1. The factory rubber pads are about .9" thick, and the VBandP replacements are wedge shaped, varying from .5" to .7" thick. Does that mean the car will only be lowered by .2' to .4'? The instructions with the kit say the car will be lowered about 1" but I don't see how that's possible.

2. The instructions also say that removing the 2 shims on each side, which are 1/8" thick each, will lower the car about 1/2". So same question, why is the car lowered more than the amount of height removed from the spring/shim combination?

3. The spring retainers (aluminum C shaped brackets) which fit tightly around the original rubber pads are too tall with the VBandP replacements and don't "retain" the spring, which is loose and slides back and forth in the retainers. Do I need to shorten the retainers? VBandP's instructions don't mention shortening the retainers. If I don't shorten the retainers, I don't think they will do anything and don't see why I should install them.

Thanks for any help. As you can tell, this is the first time I've done this.
