Hmmm, well, I know virtually nothing about coil-overs, so ignore me...
but, if "raising" the nut *compresses* the spring, how is the spring
supporting the weight of the car?  Wouldn't doing that raise the lower
spring perch and raise the car, since the spring compression should
remain the same, it is due to the amount of weight on it?  (F ~ kx and
all that)

You can also just try it each way (raise/lower shaft) and once it's
obvious to you (on one corner?), set them all where you want, make a
note of the process, and post the results here!

just my barely $0.01...
