Seriously though, we run full fire suppression systems in the race cars, mainly because we have to, but it's a good safety measure for the driver and other racers/crew. I have little concern about the race car itself. I tell all of my clients, if you ever have a fire just get away from the damn car and make sure you're safe. Insurance will take care of the rest. In nearly 3000 cars now, I know of maybe 3 fires, all aircooled. Happy to install any fire suppression someone wants though... it can't hurt and its your $$$.
@DannyP the $400 fire system doesn't install itself, so if I'm putting it in and testing it, it'll be a couple thousand ;-) Of course we do it MUCH cleaner than the 356 pictured, but thats another story.
