The whole thing was for naught -- the suspension didn't go down much. I drove it a few times up and around Angeles Crest Highway, which happened to be very local, and that did the deed.

If you know and can measure the target ride height, adjust to that and align the car. Then, just keep up with the adjusting height as the car continues to settle. At some point it will stop settling and you'll be able to stop adjusting.

The workshop manuals have a suggestion for pulling the front end down. Short of setting some more anchors in teh workbay floor I haven't come up with a way to do this. If I had a four-post lift it would be a snap.

There's also a stretch of country road where the culverts running under it (more accurately, the fill around the culverts) have settled over the years and there are some nice, smooth, wide dips. Not sharp or 'jolty' at all. just a nice smooth drop & rebound. Again, and almost perfect 'squash' of the springs without a hard bump.
