Don't personally know too much about the subject but reading the replies so
far I get the impression that adding a rear bar of lesser strength than the
uprated front one would (?) reduce the understeer brought on by the uprated
front bar and assist in levelling the rear end on the bumpy local roads,
without the need to increase the rating of the rear springs. It might
induce the lifting of the inside rear wheel when cornering hard, but then
again I rarely corner THAT hard on the long drive to work along the fairly
straight, but rough, local roads. I have the Panhard rod, adjustable gas
shocks all round, the frontline front suspension kit, hard spring shackle
bushes and poly bushes for the 11/16 front bar. I will have to modify the
panhard rod kit (the original design sucks) so will fit the rear bar and
simply try it for a few days. THIS has got to be the best way of finding
the answer to the original question.
Now, my next question is.......
Q. How can fitting a Panhard rod INCREASE the tyre scuffing? The distance
between tyre and spring is the same on both sides when at rest with no
tension on the rod but the chalk marks are worn off the passengers
side( body link end) after 'spirited drive' cross country. Could the tyre
wall be flexing an inch a full 20% of the radius behind the point of contact
with the road? The rod fixes 2.5 inches lower at the axle end than at the
body end. This angle would pull the passengers end over when the car was
bouncing down? I'm going to try welding a bolt onto the axle case near to
the bracket that goes between the axle tube and the'U-bolt spreader'. This
would bring the bar a bit more horizontal. I think this is the right train
of thought but would welcome any other comments, just in case I am missing
something obvious. Oh well, its not like I have anything else to do with my
time.......
