Richard,
It's a broad generalisation to say that the rear spring is
responsible for drivers side sagging - there are a number of other causes,
for instance a twisted front anti-roll bar or sagging front spring. The rear
spring is sometimes the cause, but often it is the pad which this rests
against in the housing atop the diff. Where there is sag caused by the front
end, this is more evident on swing spring cars BECAUSE of the lack of roll
stiffness at the back. The fixed spring of the earlier cars serves to
provide resistance against any tendancy for the front end to lean (in a
static condition), while the swing-spring allows the front to dictate the
stance of the car.
I'll let others comment on the camber compensator (Joe?).
Cheers,
Bill.
