ok so I got my new geometry laid out (had some kingpin issues and all) sadly I am raising my car back up an 1.5" (had dropped it 4") but this gets my rack in a nice place place a better daily driver stance.

(all my dynamic settings are with 1" jounce, 2* roll, and a turning rate= 32' radius)

I was told that :

roll center should stay within -1 and +12 inches mine is 4.46", and moves down .64"

kingpin between 7 and 10 degrees mine is 8.82
caster is 1.59* degrees static and has a rough gain around .30 derees

scrub radius is 2.55" (9.5 wide tire)

only thing I really need to tweak more (as I type this I noticed it) is I have double ideal ackerman so that needs tweaked a little I guess.

EDIT: just tweaked it down some...but still kinda large.

If total RC migration is limited to less than 3/4 of an inch throughout range of motion that is pretty good, in fact it's damn impressive. KPI can actually run as high 12* or so with no real adverse affects, less than 9* will be fine.
