"The most recent revisions to the bumper standard took place in May 14, 1982,
effective for MY 1983 and subsequent model year passenger cars. This amendment
reduced test impact speeds from 5 mph to 2.5 mph for longitudinal front and rear
barrier and pendulum impacts and from 3 mph to 1.5 mph for corner pendulum
impacts. In addition, Phase I damage resistance criteria were substituted for
Phase II criteria and a bumper height requirements of 16 to 20 inches was
established for passenger cars."
[end quote]

My car was lowered 1-1/2 inches... 
(measuring from the ground up to the top & bottom of the black bumper "Claude
impact area")
Stock Height:
15.75" bottom, 19.5" top
Lowered Height:
14.25" bottom, 18.125" top

Even though both heights have more than half of the bumper within the 16-20inch
requirements, the cars were still raised. I would have to guess that the
definition of "bumper height" would be to center the bumper within those
measurements. But then again, even my stock height was not "centered". Were there
some tolerances allowed? If this law was the reason for the front end raise, it
does answer some questions but still leaves some speculation.

When I said " 3. cheep springs were used to save money" I did not mean the
quality of the springs, I was referring to the price. Hypothetically speaking DMC
could have saved money purchasing 'off the shelf' springs (if available, and if
correct size but maybe a bit longer than necessary) in stead of manufacturing
their own springs from scratch (much like the Volvo engine). So in this case
cheap springs could lift a car.

[thanks for looking past my lexDysic tendencies when it came to "cheep" vs "cheap"]
