I have searched for this and I don't think I did it right, but how do you djust the rebound on Koni coilovers? I pushed the piston rod all the way down then I am supposed to turn, but first thing is I don't know what to turn and second if I am supposed to turn the piston rod, I don't hear any clicks or anything, how do I know it changed? I was told there are 10 settings too, can anyone confirm this for me?

Also, does anyone know if I need the white Koni adjustment knob and whee I can get it?
