Adjustable is always better. If you lower the car and you end up with your thrust angle being off when the axle is centered...you're gonna wish they were adjustable.
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).
