In my way of thinking the most important part of driving a race car on the salt is drilling into a drivers head how the fastest way is to egress the car in a emergency.
Nothing else is important......................... Bob
Bob has it right. I spend more time practicing the egress procedures than thinking about my shifts, throttle application, etc.
Even with that, you may be upside down and on fire, so preparedness is just a jumping off point. Keep those things in mind
when mounting any and all switches, parachute pulls, fire buttons, etc.
As for the inertia switch, we went pull-a-parting and got everything they had, about $5 a pop from Fox-body mustangs. Two
of the six we pulled didn't work ( a good shake of the switch and it should "pop"), so be prudent in testing before you shell
out the cash. We mounted ours with hard rubber bushings; when we solid mounted, the thing popped on the return road
That's on a car with almost no suspension travel and a very, very rocky Maxton track, but still...
