A slug is the English standard unit of mass.
1 lbs (force) = 1 slug x 32.2 ft/sec2 (acceleration of gravity).
The inertias are the resistances to rotating about the center of gravity
around the three primary axis of the car (pitching - horizontal cross car
axis, rolling - horizontal front to rear axis, and yawing - vertical axis).
It is interesting that they measured these. In this case they are a
combined measurement of things like the compliance of the body, springs,
tires, etc. and the mass distribution of the vehicle.
I will have to save these to my technical archives. Any info on the other
body styles, Dave?

hhhhhmmmmm....in my calculations regarding the effects of lowering on the
caster angle, I had assumed that the design orientation of the vehicle was
horizontal. This indicates that VW may have had a slight nose down
orientation......
OMG! IT WAS LOWERED FROM THE FACTORY!!!! <G>
Only kidding. But I should go back and see what effect this has on the
numbers I calculated since one of my initial assumptions was wrong. Dave,
does the report give the lengthwise position of these measurements so that I
can calculate the angle?
Will keep everyone posted.
