I've watched an Evo locking nut undone with a McGard key! I've also heard not very good things about them coping McGard designs (this comes from the guy who is the head of the Ford Security Dept at Dunton). Apparently the word is "the latest designs with a spinning shroud" is the best to get currently fitted to the new Focus & C-Max.
Oh and if you want to put two locking nuts on your wheels (e.g. diagonally opposite each other) then thats fine.
