Can you expand this explanation?
Sorry for hijack. You can pm me if needed
Put the jack stand here. On the lower A arm, to support the weight of the car. Adjusting height so spindle to ground is at desired ride height with the rear. In my case I used an angle gauge on the frame as I have adjustable fronts and fine tuned height after.
Put the caster/camber tool on brake rotor. Plumb Bob from rotor to ground for tape lines to find 20 degrees steering angle. The only load on the upper arm is weight of spindle and hub so you can adjust uppers easily.
I double checked on the tires after suspension settled as i did toe and it was good.
I may have also fluked out and been successful by accident, so there's that.
