As if I really understand this correctly. . .

If you decrease the space used by the spring by using the doughnuts then
you will increase the pressure exerted by the spring because it will be
in a more dense state because of compression.  This would cause lift in
the vehicle up to a point, that point being determined by the number of
doughnuts being inserted.  In an extreme state (state of insanity) with
multiples of doughnuts installed, you would max out the travel of the
shock without having installed the spacer or extension on the shock.

Wouldn't you damage the shock and/or its mounts by using spacers or
extensions on it without increasing the lift of the springs?  What would
happen to them when you bottom out without stiffer springs or at least
springs using doughnuts?
