Front suspension suggestions for better tracking

You could try adjustable strut rods and see if 5.5 degrees of positive caster helps.

other than that, factors would be: your tires, other alignment specs -camber/toe, rear end alignment (shown on your computer 4-wheel alignment sheet), or worn suspension components.

I don’t think shock or increasing roll stiffness is going to do anything for wondering at static cruise speed… cause the car is just going down the road straight.
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.
