I've looked but didn't really see anyone say anything other than the obvious about after doing upgrades to the suspension redo the alignment. My question is, after installing new springs and/or shocks does a car need to "settle" or be "settled" before doing the alignment. By "settled" I mean drive the car, let it sit for a day or a few days, bounce it or whatever is needed to "seat" the upgrades so to speak.

 

No. Install the suspension, drive to the alignment shop.
