I've been watching the discussion about spring spacers with some
amusement for a week or so.  A couple of thoughts have occurred to me:

1.) Anybody watch NASCAR?  What do you think "weight jackers" are?
Adjustable spring perches.  Lengthens or shortens the available space
for the spring.  Raises or lowers a corner of the racecar...

2.) Don't believe it?  Then measure the ride height, install a spacer
and remeasure.  That'll be the proof.  EASY!

Until everyone concerned tries it, there doesn't seem that there will be
consensus.

I, on the other hand, would just get stiffer, longer springs wound.
National Spring & Brake will make a spring to whatever specs you want.
