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.

 

A few miles of driving will settle it.

If you've put aftermarket springs in, turning the strut tops in the front will probably be necessary and the allignment shop may charge extra. For the rears you'll need the adjustable camber link (body to subframe) sold by racing beat, and even then the body will need notching on top of the camber link.
