yes you are 100 percent right. my car was with without a motor and on a lift for 2 weeks approx, my suspension did settle in the air and was higher at first drop… the motor has been in and running for almost a month now and the suspension dropped and has setttled but is still at least an inch higher… that is where i origionally posted… not the day i got it, i was aware of the suspension being in the air for so long… etc… but you are 100 percent right no one can measure unless under exactly the same conditions
