how to adjust a Specialized Road Pro-Stem

I wanted to lower my handlebars (a 0 degree rise with a 100mm stem) on my Specialized Allez and when I went to the Specialized website, I couldn't find the stem I wanted. Then I realized the stems they sold were adjustable including the exsisting stem I have now ! The only problem is how do I adjust it and how do the shims work? I prefer to do it myself than have a LBS do it because I have a bunch of tools left behind from building up my Surly Cross-Check.

This is the stem if it helps:

And right now, it says +16 and -8. How much can I expect to lower my bars?

From what I gather, it looks like I adjust the stem rise by turning the shim around and flipping the stem.

remove the stem and rotate the spacer/ shim that slides up and into the stem.
It will have corresponding rise degrees listed.
You might check w/ a local spec dealer to see if they have any additional spacers laying around. They come in different sizes / degrees of rise.

Do you have all the parts (different caps, etc.)? Not familiar with that stem, but you're right. If it's angled up, most you can just flip it over. If there are spacers below the stem on the steerer, you could also move some of them above the stem.

And if you flip over the stem you can use the negative numbers. With that shim (the +16 / -8 shim) you can have as much as -16 drop on the bars by turning the shim around inside the stem clamp as well as flipping the stem up-side down.

This is, of course, as you astutely noticed.
