We are going to 1100 front and 700 rear maybe more! I drove on streets for couple years with 1000 lb springs and JRZ coilovers. Was downright comfy.

1000lbs springs are still softer then bump stops

Clint's suggestion is definitely the fastest, least expensive change though. Long term I would look at something more like 16kF/10KR if you otherwise like your current setup.

before any spring rates get changed around, i think that rear Hotchkis needs to go and be tested with stock. then further tuning from there.

I see Shamu is at 8k difference now but would like 7k and bkleeman is within that range.

with both the weight balance of the 370 NOT being 50/50,. and the high amount of both front grip potential with sqaure tire setup, decently high levels of unsprung weight, and the wishbone suspension, i think the front really needs a good amount of rate. depending what rear rate you need depends on spring location (stock or true coilover), sway bar selection in back (large, stock, or none), power level, and LSD.
