Aha, thinking about it more, I can see I'm gonna lose  a bit of travel 
using a spacer, too, about however much the height of the spacer is, I 
guess - but it'll take somewhat more force to bottom it out than it did 
previously.  I actually got around to doing it this afternoon, and am 
glad I changed my plan from 2" to 1.5"  for the spacer, as that seems to 
have raised it 2 or 3" - just got finished about dark-thirty so haven't 
taken it for a drive yet.

It's funny, I could understand that the other day after reading the info 
on the website, but its escaped me for right now how that works- I may 
have to see if I can get some to experiment with when I'm hauling 
materials in the Jetta.

Ah, I see...
