[Spridgets] [midgetsprite] Rear sway bar

[Weslake1330 at aol.com]

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.
