The F-41 option. I always got it on my company Caprices, year after year. That and limited slip with snow tires in a Minnesota winter would get you most places.
Actually, not to split the hair (but here goes) in 1995 the sport suspension was one up from F41.
It went: stock (slusho) - F41 - sport - LE(which is what came on the SS).
Sport + the LT1 makes one nice, if a bit long in the tooth, ride. She's shopping; I'm trying to figure out where to put the Chevy and keep the neighborhood nazis off my back.
