If you are referring to anti-theft system and seen that you live in Brooklyn I would put anything I can get my hands on. At least the club is visible and It might deter someone unless they are so desperate to steal a Z. But remember that no system is totally 100% secure and there are always ways of deactivating/disabling anything.
To me the best system is a garage (a home garage) not a public garage, and even inside my garage I lock the vehicle. Read these two and might give an idea of what thief are looking for when selecting a target vehicle. Good luck.
