It goes past 16 clicks, but after 16 clicks it doesnt change the damper setting.
I confirmed this with Fulcrum, it will just click but it wont get any softer.
Tein recommended 345mm all round, and 12 clicks from the hardest (so the 4th softest setting)
I've got mine on 345mm all around and 4th softest and front, 6 softest in rear to try and control the springs more.
