(50",y,30")
I know the X and Z coordinates would actually be a function of Y but for small angles I think this is negligible?

The Hancha user is me (or plucas) ;] I used the vars x, y, and u for the transfer function rather than x1, x2, etc. since it makes it easier to keep track of the variables. In terms of the car as a global coordinate system, I use the X, Y, Z variables as stated above.
If we can create a sophisticated enough model, the suspension would see movement in all three coordinates along their respective arcs.
