Update: Man oh man, the 1/x turn(s) adjustment on these Konis seems so unreliable. I had the same experience with the rears: adjust to full firm and then adjust by 1/x turn(s). I adjusted them by the same amount; then I compressed them and timed how long it took to them to fully rebound -- they weren't even close. Am I nuts for adjusting them based on the timing of the rebound instead of the number of turns? Are they compensated in any way for the weight of the driver?
My car has been running Yellows and Eibach Pro-Kit springs for a while now and for my purposes they're great. For street driving they're set to full soft and it rides significantly better than stock while still feeling well controlled. For HPDEs I adjust to full stiff -1/2 turn for the front and roughly -1/4 turn for the rear.
