Von,
These are the instructions they gave me when I got mine several years ago:

Top Hole – Hardest Hit (start here)

Bottom Hole – Softer Hit, moves IC forward

More Pre-load, Softer Hit

Less Pre-load, air gap, harder hit

If car pulls to the right add a quarter turn of pre-load to the right bar and visa versa.

Set front shocks soft

Set rear shocks on #5, if car wants to porpoise go to 6 or 7 (harder).

If car spins, needs harder hit, go softer

Too much wheelstand…. Softer hit, restrict front travel

Good Luck,
Bill
