I've tried several settings at Streets, Buttonwillow, Roval, Spring Mt. and LS but after some fiddling, I just put it on full stiff (all the way in) on all four corners and full soft on the way to the track.
Occassionally, I'll soften the front one or two clicks if the back end is coming around on turn exit.
I run the Falken Azenis 17/18 (35psi F, 35psi R), Comptech sways (mid hole F, aft hole RR).
