As long as the same thickness shim is used front and rear the gearbox will remain level and only the hinge pin angle will change.
My kit only came with two options (0 and 1) but if you look at the parts diagram in the manual it shows 3 different pairs. (Hence the 3 settings on the set up page)

Not strictly correct... its all above.
You have to run the 0 curved shim on top of the rear block at all times.
You use the square shims under the front block, 1, 2 and 3mm for 1, 2 and 3 degrees of antisquat.
If you run 3 degrees of antisquat, then you do not need a shim on top of the front block.
If you run 2 degrees, then you need 1mm on top of front block.
And likewise, is you run 1 degree then you need 2mm on top of the front block.
Basically, both the front and the rear must be a total of 3mm of inserts. Otherwise the chassis bends round the bottom of the gearbox and induces a loss of antisquat, or as I found, positive antisquat.
