I have run the PSS9's on the street at all settings now. I think that the 9 available settings are more accurately three settings (1-3 = hard, 4-6 = med, 7-9 = soft). I can't tell any difference in between.

F/R soft gives nice ride quality on the street/freeways. Medium F/R is a nice compromise. Hard F/R is great on the track but a little stiff for a daily driver. It seems best to set the fronts where you like them (1, 4, or 7) and then go two numbers higher in the rear (3, 6, or 9).

Of course, your preferences might be different.
