Even if this is true, the fact remains that the space the spring fits into is
determined by the length of the shock, not the length of the spring. Hence, the
more dounuts used, the smaller becomes the space within which the spring resides.
To get "lift only," you would need to insert the spacer on the shock mounts, not
the spring. Adding to the length of the shock will raise the vehicle without
changing spring charistics at all. And adding donuts to the spring does nothing
to "lift" the van, beyond compressing the spring. How could it when the maximum
suspension extension is determined by the length of the shock, not the length of
the spring.
