Spring Rates ?
I'd like to know if there's a difference between the oem z28 springs and the standard SS springs and if so, what is it?

From what I understand, a 292 lbs/in spring compresses 1" for every 292 lbs, but I have been wrong before. (see above post)
I do wish to add on thing. Stock springs while 292 or so (they vary a little) in front, are under a tremendous amount of pre-load. Just sitting assembled they are compressed some 4-5". They are soft, but also long. And lowering springs have very little preload which has to do with why the lowering sprinsgs when used with proper dampers don't ride as badly as many think. Certainly much firmer, but actually less harsh at times (again, the shocks have a lot to do with this as well).
