Personally I do not use safety wire on my Cobra. It absolutely will not prevent the knock off from loosening and coming off unless the vehicle is stopped imediately, the wire will break. On my Cobra I use two points of reference to check the condition of my knock offs, I put a paint dot on the knock off that lines up with the wheels valve stem. As you do your walk around of the vehicle before driving you can easily see if the two are out of alignment indicating something is wrong.
That being said I do use it on my clients Cobras as a visual aid when they do a walk around before driving the car. The way I use the safety wire as a visual aid is that I put enough slack in the wire so that it creates a bow from the point that it attaches to the wheel and the point at which it attaches to the knock off, rather than a straight line as you would do with typically safety wired hardware. By doing this my client can tell if the knock off is loose or if everything is ok, a loose knock off safety wire will have a straight appearance because the wire is be stretched during the loosening process and has the bow no longer preset. A bowed appearance will indicate the knock off is tight.
