This is from my copy of "How to make your car handle" published in the
70's.
k = 500,000 x d^4 / (.4244 x b x a^2 + .2264*c^3)
k is the single side rate for a steel bar
d is diameter, b is length of straight center, c is the arm length along
the arm, following any bends, and a the offset from the straight section to
the end of the bar arm at right angle to the bar.
For a hollow bar do the same thing for the "hole" diameter and subtract
it from the solid bar.
x is multiply. ^ is exponent

Subject: Anti-roll bar stiffness
Anyone have a formula handy for calculating the stiffness of a tubular
anti-roll bar? TIA
