coil springs

Does anyone know of any company that makes springs for the cv? I can only find moog springs and I can't figure out what the (compression rate?) is for them, it only says variable rate (mog-cc849) or the other set(mog-cc865). I was looking for something a bit stiffer than the springs that come on the base model(99 cv), but not as stiff as the police model. I will be adding 4 new kyb gas -a-just shocks and the new front springs too. Any comments, thoughts or ideas would be appreciated.........thnks:banghead:

I would find some lincoln towncar springs, The ones with the coils ride pretty nice and are heavier to compensate the bigger tub on the back of the towncars.
