If you look closely you will see that there are a number of holes on the wheel side as well as on the WAS side, these serve to keep the angle within the 90 degrees that the WAS can handle.
this way you can keep a large steering angle within the tolerance of the WAS, just long bar on the WAS and a short one on the wheel side.
And those supersteers that turn briefly, I know, but the axle turns simultaneously with the wheels, right? then I would put the WAS at the pivot next to the wheels.
good luck!
