The new fire system requirement in the GCR has got to go. As far as I can tell, it serves only two purposes:
1. To put more money into the hands of SFI. You cannot be certified w/o paying their extortion-like per-unit fee.
2. To put more money into the hands of people who make these systems. If you're system is discharged, you no longer can refill it yourself. You must have it refilled by someone who is "certified". I.e. see item #1.

Can someone please explain to me the value-added to the racers by this requirement?

Frankly, if you are contemplating building a car, I advise you to buy the rollcage/logbook of a wrecked older car. The logbook goes with the cage, not the car. I.e. all of the grandfathering goes with the cage.

I'm really getting angry.
