most of Cradle should have same road clearance as front cross member. Just park on flat level pavement and measure them to ground.
Alignment should be done without anything in the car. No crap in front or rear etc. Most shops don't tell you to pull crap out before doing alignments.
But note that Static alignment done in a shop often won't matter for cars w/ bad suspension parts or lowered cars.
Example: Iffy Cradle and CA bushings alone can steer the car and often in random way as you hit the gas, brakes, or both, or just hitting a pot hole.
Note too many replace the front shocks and not the rear or other way around. If they install gas units then can change road clearance for the axle.
Fiero load rating (GVWR) is calculated w/ 2 adults and 100# cargo but doesn't tell the whole story...
The two adults = ~ 175 lb each = I think ~ 50-60 percentage male model adult (Male Crash test dummy) at the time.
If you and passenger are over then wave good bye to having 100# cargo w/o going over load limit. This will hurt engine and brake performance at minimum. If only a heaver driver in the car then can change alignment some to a lot because car is loaded lopsided. Worse if you have iffy bushings etc.
Many new Owners Manuals give less guessing and puts simple calc/charts saying GVWR − Total People Weight = Cargo Weight Available if any.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
