Er - the spring industry has long since proven that theory wrong, at
least in application of steel in springs.

Springs sag.   The automotive industry is the classic example of proof
- leaf springs sag, coil springs sag, torsion springs sag.    Maybe in
the majority of the cases it's related to overloading - or simply
continuous loading near their limits - but at the end of the day,
springs sag.

And baywindow buses, campers and passenger buses alike, have a
particular history of this.   But so do 911s, 944s, beetles......(and
split busses.  but bays got significantly heavier in the rear...)  And
they tend to sag in the rear, not the front.  Probably because they're
all rear-heavy, but maybe the quality of the torsion springs and
mounts is part of it.   Either way, the fix is to readjust them.
Replace them if you think you should, but the availability of new
parts is probably not what it once was... :)
