Sorry, I had a virus that I cleaned off my home computer, that took out my Windows...
Spring rates in the 275# area might be fine for the street. Thats basically a little more than stock rates. I would start with 300#, on the firm side. Personally I run 8" tall 425# coilovers on the front and 350# (too soft for me) "regular" (non-coilover) rears. THis is for a Griggs tubular front, and my own design t-arm/panhard rear.
