they use 450# or 400# for the front, I am running 425# and like that so far

Coilovers for the rear got moved to the backburner again due to other issues that have come up

Marc H suggested to me to use 425/300 springs for my car. My criteria was I wanted tour to be more like sport, sport more like perf, and perf to be a little on the rough side for the street. Currently I drive in perf all the time except short bits where I know there are rough patches. I'd like to drive in sport all the time.

I've never installed them though, so I don't know. Looking at the leafspring rates, 300 is less than the Z51 rear rates, and above the base rate. 425 front is more like the '92+ cars that had softened front spring rates (even the Z07/Z51 cars). I don't want softer fronts, so if I ever did install them I'd go much stiffer front like 5-600.

Did you have to relocate the sway bar to do the fronts?
