Glad you like them.  Once you find the sweet spot, you never have to touch them again. Mine is 1/4 turn of preload on both sides (w/ driver in the car) and the shocks set as stiff as they'll go (Rancho 9 ways set on 9). If the track isn't that great, I loosen the shocks a couple of clicks and/or drop the air pressure a little. Every car is different though.
