I'm almost certain you need more caster and possibly more toe in.
If you have the strut rods you wil probably find there is a bit of bind at the "up" travel limit. My car is pretty low in front and I get just a little bind at the "up" travel limit.

I run about 7 deg caster and 1/8 toe in measured at the tire center line. About 1 deg neg camber (top of tire is closer to the center of the car.) Other than the car is a bit heavy on the steering for a light weight car it tracks very well and is rock steady in the cross winds. It actually handles pretty well for a big tires, little tires car. I did a funny car high speed back up just to relive the old days and it does ok there too. Often lots of caster would cause death wobble backing up.

Death wobble usually occurs when the alignments are very close to "0".
