It is possible that even when these springs are
fitted, the owner may still desire more damping. Should this
occur, there is a scheme for supplementing the standard hydraulics
with single type Hartfords at the front and rear. They are
only required for abnormal conditions. When fitted on the front
they improve the high speed steering. The best all round setting
for fast touring is 40 lbs. It should be impressed on the
customer that a load greater than this will make the car ride
harshly. The Hartford should be slacked right off for normal
conditions.

The steering is somewhat improved at high speeds
by increasing the pivot lean to 2.75° backwards lean. 3° should
never be exceeded or high speed wobbles may be brought up.
