Richard,
You are correct sir! But (and there always is a but), if you lengthen
the axles without changing the length of the spring the upright will
change angles (to the ground not the axle). This is because the spring
is the upper control element and the axle is the lower control element
in a swing axle setup. When the axle length is increased, the angle of
the upright must also change.

Not strictly true - the angle of the wheel is NOT determined by the
angle of
the suspension upright. The wheel is fixed at right-angles to the
driveshaft (except on roto-flex cars), so the angle of the wheel is
dependent on the angle of the driveshaft, and nothing else. The
suspension
upright should be able to pivot where it connects to the hub, although
it's
usually pretty stiff.
