Just got back from the alignment shop and took the car on a spirited run on some local backroads. This thing feels planted and has significantly less understeer.
The alignment shop set my rear toe to 0, found that the car has about 1.75-2 degrees negative camber in rear. They set the front to 1.375 negative camber, and about 8.25 degrees caster, and 0 toe.
I did also find that passing over a uneven construction plate on a backroad at speed used the full travel of my suspension. I'll have to watch for those in the future.
