It looks like they can be set from a range of .8" lower up to 1.5" lower according to their marketing. You probably have seen these, they contain the minimum and maximum acceptable range of adjustment for the spring collars. These are for the v1 but since KW said that v1-v3 all use the same springs, these settings should be the same across all 3:

Edit: I found the V2 setup instructions and they appear to be identical:

They probably use the exact same strut body, springs, collars, etc, with the only difference being the adjustment capability for the damping.
It looks like you can use the dimensions for "A" to set the coilover in the approved range and then you can use "B" as a check. Or you can pick you desired "B" setting and map it to the proper part of the range of "A" to get you close to your desired setting as a starting point.
