I went with the Hotchkis, they're progressive rate springs so they offer more resistance as they compress. Drop Specs: Impala SS 1.25" F, 1" R 90-96 Caprice 1.5" F, 1.25" R.
From what I have read on here, SS and 9c1 springs have the same spring rate but are different heights. The Hotchkis are as low as I would go with an everyday car.
Spring rate info
here.
Rustic Racing sells Vogtlands, which are the same springs Hotchkis uses, for $195. "These springs provide a 1.2” drop in both the front and rear of the 94-96 Impala SS. You will see more drop if you are swapping out 9C1 or civilian caprice springs."
