[Shotimes] Does a 24mm Rear Sway Bar Exist?

[Alan Fanning]

The current rear bar is whopping 21mm, mated with an equally impressive
(j/k) 20.5mm front bar.

IIRC, torsional bending resistance is a function of radius cubed, so for the
sake of science we can run calculate some rear/front ratios (as I recall
John Hrinsin once doing - but I failed to keep the post):

Rear    Front   Ratio   Ratio^3
 26      24     1.083    1.27
 26      22     1.182    1.65
 26      20.5   1.238    2.04
 25      22     1.136    1.47
 25      20.5   1.218    1.82
 23      20.5   1.122    1.41
 21      20.5   1.024    1.07

So, a 23mm rear bar might not be a bad combination with an existing 20.5mm
front bar. It would provide a little more of a "plush" ride, in keeping with
the intention of using this particular car for touring and getting the wife
around town.
