I had my springs of the coilover settle in for about 400 miles before I got an alignment.
Make sure you are happy with the height before aligning though because if you change the height after the alignment, your toes go out of spec.
The highest setting on ff is about 1 finger gap so that'll work if you're satisfied.
But the roads aren't too bad in the norcal, except for downtown SF, those roads are ****.
I've driven my old accord at 23.5" to LA and it was fine, I've driven 23.25" in downtown SF, milpitas, oakland, past Vallejo, and etc a few times and survived.
It's just how you drive and pay attention to the road. I always keep my eye on the car ahead of me, if they dip on at pothole I have a chance to avoid it. There's a lot of people who DD their car and is 23" from fender to ground, just have to know the road and how to avoid bumps.
