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.
The  rear will want to slide first.
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.
By  selecting the right combination, the handling of the car can be tailored
to the  driverbs particular style or to the needs of a particular  track
