Front suspension suggestions for better tracking

Those are his rear alignment measurements.

I wanted to check if anything was weird back there. Super stock springs should make one side of rear higher than other. Buddy has two A-body MP sets bought 8 or so years apart. They gave different results.

Oops, should have read closer.

Well, what are the rest of the front alignment specs? +3.5° isn't a ton, but 235's aren't crazy wide either.

Thanks. The tires are new. I should add that I have 18" wheels, 6" front 8" rear. My rear springs are super stock. All other suspension components seem to be in good condition. One other thing I forgot to mention, is that the spindles seem to be a bit short. The technician had to add a washer to the nut in order to tighten it down.

Wait, added a washer where? Under the ball joint or under the spindle nut?
