With your struts spaced down 2.5" and everything alse in it's stock location, your bound (no pun intended

) to have CV carnage at full drop. I would bet that they will over extend and pull the inner CV past the retention clip and seperate. I would do some form of diff drop to keep this from happening. I also would check the center link of the rear suspension. I dont know how much lift the TJ coils give, but make sure it is not binding (directly above where it attaches to the 3rd member.
Also I have heard that a 2"spacer witt throw your alignment out, causing the need for camber bolts.
HTH,
