should work fine. when i lowered mine about the same amount i got the drop links but i didnt really need them (used them anyway) - no rubbing or anything lowering that much. not sure if you'd be able to use the spacers still on the rear when lowered. might need to stretch tyres if you do at that height.
this thread may help. go through there and see if you can find something similar to the setup you'll run!
