dealing with would present other problems, but even so the principle always
applies. Increased roll-stiffness in the front = more understeer and/or less
oversteer. Increased roll-stiffness in the rear = more oversteer and/or less
understeer. >>
Historical notes, FWIW: the Triumph Herald, when originally being developed,
had no front bar. Testing quickly determined that the potentially, er,
substantial oversteer was not a good thing, and a front bar was added.
Similarly, when the swing-spring was adapted for the Spitfire Mk IV, the
diameter of the front bar was increased significantly to compensate for
increased oversteer in the now-softer rear suspension.
(I think I have that right! :-) )
