Good point / understood / agreed . . .
Checking my latest alignment, I have 0.07 degrees thrust angle. I assumed that was a good as it could reasonably get. My car is lowered 1.25" in the rear and recentered with adjustable panhard bar.
Should I be concerned / should I try to improve that? (I would need adjustable LCA's to do it).
If the amount of thrust angle is within the ford alignment specification you should be fine. When I had my alignment after lowering the car they could not get thrust perfect without the axle shifted over to one side. So I said center the darn thing for aesthetics and I never noticed a difference. I had fixed poly ends. Now I have adjustable with poly one end. I can definitely hear them but I don't care yet. I am happy with adjustability, especially with other suspension component modifications. Thrust is likely still off some because I have made adjustments and have not been aligned again.
