Picked up a set of red Koni Special D 82L 1722, with a spring measuring 13 3/8" and no color marking from a member. Was told they are stock springs but repainted.

Help with how to set the adjustment and to what setting? Is this just a push the shaft full down and turn the shaft to adjust the shock? Are there clicks or just so many degrees of a turn? And, for daily sport having fun driving, how far how much of a turn is a good setting?

As always, Thanks.
