[T3] Caster angle and Wedgies!!


Jim, I have to agree with Keith on this one:

Caster is lost anytime a car is lowered.  Look at the angle that  a line
drawn between the two ball joints make at a given ride height.  When the
lower arm is "turned" on the torsion beam to lower it it affects the
angle that the lower ball joint is at.  The line  is now closer to 90
degrees than it was before the torsion arm was "turned".  The principle
is exaclty the same as in Beetle front end lowering.

Gene Berg, and possibly others, sell "Caster wedges" which are designed
to fit between the Beam and the front bulk head.  What they do is "move"
the lower edge of the beam outward toward the front to bring back the
angle that was lost when the car lowered.  Mostly drag cras use them
because they offer high speed stability.  GET IT!!  These kits also came
with longer bolts and on severly lowered cars, one could stack two if
the wedges.  This also required slightly longer bolts.

Given that, I was poking around  underneath my Fastback, Inge, to see if
caster wedges would work on Type 3 front  beams.  With longer bolts, I
think one could fashion something that could work.  Has anyone ever
thought about this??
