I've had mine on for awhile....The car hasn't been driven, but they have not settled.

QA1 makes 9" springs. I think they're the ticket.

I'm gonna post a picture of my rear shocks.....the control arm bolts are 5/8" for sure....Look at the head of the coilover bolts and see if you think they're smaller than the control arm bolts. I'm sure they are....but this picture could be playing a trick on me.
