Okay, here goes. I'll not share everything because, obviously, protection that is posted publicly is a vulnerability. (It took me a while to determine what I could comfortably disclose in this post, hence why the information is sparse.)
There are several night-vision video cameras stealthily mounted in various locations of Ray's car. Great for racing and for security.

Two forms of recording equipment: one on-site and one off. Although wireless (i.e. X10) is easier to install, he recommends having a wired setup for better quality video.
He hints at something Kane mentioned as well, only involving light rather than sound. Evidently a tactic used in newer police cruisers as well.
There are other forms of non-video security; some he shared with me and other things that I don't know about either. (Good level of protection not to disclose everything to essentially a stranger you meet on the Internet

) Clearly you'd have to be incredibly stupid to try and break into Ray's car. The work involved to get at every little detail is incredible; I have to give Ray major props for electrical work to his car.
