RE: over-steer, under-steer, neutral steer...thoughts,

["Navarrette, Vance" <vance.navarrette@intel.com>]

        Think of it this way;

        When you understeer, it is because the front tires are being asked
to do 
more work than they can handle, so they give up and slide. The way to
correct this
is to get the rear tires to do MORE work, and take some of the work load off
the front tires. 
        You make the rear tires do more work by adding/stiffening the
rear sway bar. This holds the rear tires against the road more securely, so
they can
do more work and the front tires need to do less work as a result.
        The outside front tire must do more work than any other tire when
cornering. The
cornering force added to the weight transfer means that the outside front
tire is heavily
loaded. In addition, the inside front tire is not perpendicular to the road
because 
the car leans when cornering.
        The rear sway bar holds both rear tires more firmly on the road,
*AND* it
reduces lean. This in turn decreases weight transfer to the outside front
wheel, and
further decreases the work load on this tire.
        So, the rear bar increases the work load on the rear tires, and
reduces work 
load on the outside front tire. It is a double win, and higher lateral
g-forces are the
reward....

I was afraid of that Vance, but it still makes sense.  Wait, no it
doesn't now that I think about it.  Wait, aw hell.  

Work with me, if you have a front only sway bar, then the front will
corner flatter.  That will help the tires stay in contact better.  The
rears will have a harder time so it would seem that that would lead to
oversteer.

Now, I know that I'm wrong, but I'd like to understand why.  

Oh well, changing the front and adding a rear bar are on the list of
things to do.  And tires, wheels, engine, paint, and...
