are some live axles that compensate for the driving torque, but
is a compromise: Normal bump characteristics will suffer
Additionally, the length of the original Ford
top-loader transmission makes
the drive shaft so short that
wheel travel would
have to be limited, resulting in the
bad choice of the shocks
bottoming out, or having to resort to unacceptably stiff spring rates.
Below, you can see the rear suspension /subframe
mounted in a bare chassis.
The subframe is mounted at the top, through urethane

suspension also used a subframe and trailing
arms - which worked
quite well in the lower powered car. We found it necessary to
up the mounting system to make more precise handling.
Some other kits also
use the Jag suspension,
but because of space and design restrictions, don't
use a trailing arm. This puts the
lower control arm into
stress modes for which it was never intended. With power on
off, the arm will flex forward and back, changing the toe-in
