[Spridgets] Rear sway bar

Actually, a live axle car can and does exhibit camber change at the rear 
wheels when the roll stiffness provided by the springs is inadequate.  A 
rear sway bar can be used on a live axle to adjust roll couple distribution 
where needed.

I don't think much of that was correct.  Without putting down several
thousand words it's hard to explain so I'll correct the mistakes instead.

Fitting an anti-sway bar at the front of the car is to reduce roll that
leads to wheel camber change at the front of the car that is a handling 
problem.
It does not change the fact that the Spridget oversteers, rather  it 
corrects
a problem at the front of the car.

The back of the car doesn't need an anti sway bar because the Spridget has 
a
live axle and so no matter how much the body rolls the wheels and tyres do
not  exhibit any camber change.  Fitting an anti-sway bar on any live axle 
car,
including the Spridget creates an enormous amount of oversteer.  So, unless
you're a suspension guru and ace driver you'll want to stay away from even
thinking about it on a live axle car.

A panhard rod cannot balance the front to rear suspension, rather it is 
used
to prevent lateral (side to side movement) of the rear axle to the 
bodywork.

I don't race.

Hello  Michael,

You do see about Panhard bars  tho.!


basically the handling charachteristic of  the Spridget is to
oversteer. that is the rear end  tends to come around on ya if you
overcook a corner.  the antidote for this is to put a sway bar in
the front  ..Yeah, it's counter-intuitive. You can tighten up the
WHOLE suspension by putting too large a bar on the front, then
using a panahard bar at the rear to rebalance the system,  OR
choose a smaller bar at the front to achieve an  initial
balance...


Or i  could be all wet and not know anything at all about any of
this and you should wait for one of the racers to weigh  in...

Mr.  Lieb?
