On the Spridget the roll stiffness needs to be considered in conjuction with
a live axle. If the rear body rolls at the rear (and it will) both rear
wheels stay upright. On a car with independant suspension if the rear body
rolls the rear wheels no longer stay upright but experience a change of camber.
On the Spridget the rear wants to slide first.
Yes, it's possible to get the front to understeer by going too stiff on the
front sway bar.
HOWEVER, you can still provoke an understeering Spridget into oversteer on
the entry to a corner by a large throttle input. Precisely what happens
depends on the type of diff the car has, how much throttle and stuff.

The other important function of sway bars is to tune to front and rear roll
stiff nesses to affect the degree the roll couple is take at the front of
the
car versus the rear. If you have more roll stiffness at the rear (depending
on the car this may mean running a rear bar of just running a light bar in
front) most of the resistance to roll of the car will be taken at the rear.
This will more heavily load the rear tires and will tend to make the car
oversteer, which is defined as the condition in which the passenger is
terrified.

If you run a very stiff front bar most of the roll resistance to roll of the
car will be taken at the front. This will more heavily load the front tires
and will tend to make the car understeer, which is defined as the condition
in which the driver is terrified. The front tires will want to plow
straight
on ahead toward guard rails and barrier walls - regardless of how tight the
driver grips the steering wheel and seat upholstery.
