forward engine they get such a
large moment of inertia for the car
that they, with 4 1/2" front spring deflection,
can get as good a ride as Cadillac's do
with 8 or 9" deflection. I shall be able
to evaluate this when I have tried the
cars. Generally speaking, however, the
view is that Engines must move much
more forward still for frame stiffness,
for economy of Chassis etc. If this is
so, our cross tube carrying the coil springs
becomes an obstruction.
I have your wire. It seems to
me I can easily spend three weeks in
Detroit or more and learn something all
the time on independent suspension apart
from anything else.
At the moment I am not
planning to sail until about March 15th
unless you cable me to the contrary. I believe
I am more use here than in Derby for the
time being.
