Well I rebuilt the front end on my 68 Barracuda last winter with polygraphite
bushings. Even with the graphite impregnating they started to squeak after a
couple of months. I had heard that that was an issue with the poly bushings but
I figured that the graphite would solve the problem.
I certainly haven't see enough of a handling improvement to make it worth the
aggravation of the squeaking. I also haven't seen a significant increase in the
harhness of the suspension that I have heard people comment on when making the
switch. I will likely rebuild the suspension with stock rubber bushings again
this winter.
Longevity was not a consideration when I made the choice but I can't see how
they would out live rubber. A rubber bushing has no moving parts, the inner and
outer shells are bonded to the rubber and they allow motion by the rubber
deflecting. Where as a poly bushing has the shells rotating on the poly
material. Any dirt and grit that gets in there is going to wear away the shell
and poly material.
FWIW, the motivation for making the change to poly bushings is to get rid of
the deflection and movement in the bushing pivot for more precise handling.
