I used to have an emergency fuel cut switch with a key dongle that looked like a large unshielded usb on my Z32. It could be used in an emergency @ the track or for theft protection.

Another cool thing i used to have was a micro momentary push button located somewhere along the steering column. I unplugged the momentary switch on my clutch pedal, the one closer to the firewall that engages when you press the clutch down to the floor to start the car, and wired it to the hidden button so you had to push the button while turning the key to start the car. Best part is you do not have to cut any wiring, just use small spade connectors that fit into the harness connector, tape it and zip wire out of the way.
