Setting ride height/alignment with no motor

Sorry guys, maybe I'm not explaining this correct.

You measure from the LCA pivot to the ground to set the ride height, this number is in the service manual. You do this before you touch your UCA adjustments. After the ride height, then you align the car. Do this with the motor in, out, big block, slant six it doesn't matter. When you add or remove weight, you set the ride height back to that same number (LCA pivot to the ground) and your caster, camber and toe will be exactly the same.

Now if you align the car then add or remove weight and do not set the ride height, your numbers will be skewed and your car will ride and handle very differently.
