I was wondering what may be the best theft prevention method for an ej1? Any suggestions?

 

I have a Momo Course with a quick release hub, works like a charm so far.
I leave my windows/sunroof open too all day.
Sure they can take components, but not my car.

My ghetto version of a "cheap anti theft device".
(Until I chose an alarm system for my needs).
* going to close windows now, the darkness has fallen...
