Setting ride height/alignment with no motor

im an alignment tech at my job and would like to say it will be a complete waste of time to make any adjustments without the motor and tranny in the car. every single angle changes once ride height changes. you move camber, your caster is going with it, you move toe ( most of the time) camber is going with it. i would wait til car is running and then set ride height to what ever is desired, than take to alignment shop to and get it all squared away my .02
