Allright, I've decided to bite the bullet and here's my plan.
I'm picking up a set of scales to weigh the car (obviously for distribution and wedge measurements). Calculate roll center, and somehow find a rough CG. Figure out where I want the roll center to be, and what the geometry needs to look like, including camber and caster curves. Calculate ideal spring rate (based on desired body roll for desired camber curve), then get new struts and coilovers with ideal springs.
Get back on the scales, coordinate distribution and wedge. Re-calculate roll center. Rinse and repeat a couple times.
Might take a while, but it's doable.
Which brings up one question. Of the popular coilover setups, what's the spring diameters used? If no one know offhand, I'll just contact the manufacturer but I figure I'd throw it out here first.
i thought i was picky when i got my suspension, yikes
US "standard" coils are 2.5"
Most of the kits use that size.

So the coils used on the J cars aren't metric then?
On a coil over set up that is the way to adjust your car. And when all weighed out the driver gets in the car and then it is done with him/jher in it. No the measureing most of us do. We may be putting more weight on one side or corner even though the car looks even to us.

I'm not just trying to make the car "look even"....
The springs on J-Bodies (Also N-Bodies, W, H, and a few others) are 4" ID.
Yes, the springs are listed in metric, but 64mm (the center number on your spring, which is the ID) = 2.5"
So the spring in your picture James is a 6" free length 2.5" ID 525lb/in right
Keep us updated on the GC/RC testing.
