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? >Incidentally, rocker to ground height is given as 8.8" at the rear and 8.6" at >the front. Rear damper mounting to ground is 5.2", and rear of engine >compartment cover to ground is 37.2". I assume that was before they started >putting it through the various tests! 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.
