Thanks for the suggestions.

I've got a nitrogen fill setup on the way. When it gets here, I'll get a bottle from the welding gas store and gas up the rear shocks.

I also heard from David Pozzi who's tuned Bad Penny, which has the same front and rear suspensions I'm using, as well as the One Lap Camaro, which uses the same rear suspension.

David's suggesting I leave the rear spring rates alone for now and drop the front springs to 350 lb./in. He noted that 350 lb./in. springs in the 21st Century Street Machine subframe would be equivalent to a 600 lb./in. spring in a stock subframe, which suggests that the 450 lb./in. springs in there now are the equivalent of a 770 lb./in. spring in a stock subframe. In any event, I'll swap out the front springs, leave the rear alone (other than gassing up the shocks) and see where I am.

I'll consider shocks if I can't get it where I want it any other way, but springs are about $70 a set, and gas charged shocks (which I need because they're mounted upside down) are going to be $400-$1,000 plus a set.
