Hey Tom,

If you section the strut tube correctly on the Z you can move the shock up and down in the tube using different length spacers in the bottom of the tube. Of course that assumes you are using a shock that is shorter than OEM that gives you the dampening you want. You have about 1-1.5" to play with. That way you can center the shock while getting the ride height you need. At least it worked that way for me.

In the back, you have even more to play with since you leave the tubes a little longer when sectioning.
