what are the different spring rates for W-body's with the rear carbon fiber leaf springs? I want to lower the ass of my 92 cutty but i dont know what year leaf spring i should be looking for for the weaker spring rate... only looking for like 2" - 2.5"

I can look it up, But from what I remember, it was for example the "El-cheapo" plain-jane lumina that had the lowest rear leaf spring rate (FE-1).
Yours would have the FE-3 (stiffest) leaf spring and largest diameter control arm.

Just look for a older w-body that lists the FE1 option on the part list identification tag in the trunk on the spare tire cover.
