Don't know about the specs people are using, but this thread looks as though it might be addressing what your asking.
PICS: Installed BC coilovers (BR type)
If that doesn't answer your question PM IMPORTIMAGE. He has the owner of BC's personal cell and he'll walk you through the install. IMPORTIMAGE also has adjuster extenders on his web site. I'd like to know if they would work with the inverteds.
