As far as the fire system, it just buys some time for you to get out. I t often doesn't put the fire out entirely. Those seconds though, can equate to months on a burn unit...

As far as the cage, we might take that one step further. Is regulating the number of mounting points necessary? If it meets CCR specs, and does not go through the firewall, does the rest really matter in terms of performance? Any incremental increase chassis stiffness is small when you are not tying in the front suspension, and more mounting spots allows us to at to strengthen the cage, tie in the seat mounting, etc.

Thoughts?

One of the beauties of the 944 platform is that it has a very good torsional rigidity from the factory.

The car that has won the last 3 of 4 Nationals does not have a bar across the strut towers.

If you have a street 944 jack up one corner and then open and close the doors. It should open and close easily if the chassis is not bent. This is with no cage.

I am all for adding strengthening tubing to the cage. Especially from the drivers Nascar bars to the door sill.

As we all know triangulation of the cage is what gives it strength. So if you add foot bars make them in a triangle to the fire wall. Add padding to the bars on the drivers side anywhere your body can come in contact with the cage.

One of the issues is if you race this car in other sanctioning bodies or other classes in NASA it may not be legal.

Eric, I went through the Hanksville website but did not see the seat mounting kit. Do you have pics or any info on this?

I am getting ready to mount a new seat in my new 944spec car and wanted to look at all options.
Sliders are nice but I have not yet seen one made for racing.

Having been in two on track fires and one off track I can say that I simply do not race without a min. 10# system installed. To me it is no different than going over the car to check bolts or checking your belts...basic safety.

In 944 cars I never felt the fuel cell area needed a nozzel. I would and plan to on my current car run 2 for the driver and one for the engine over the fuel rail and exhaust side of the engine. Too many nozzels reduce the discharge duration and limit the ability of the system to kill the fire. This will be debated I am sure but it comes from some direct experience.

I feel use of the stock seat mounts are sufficient especially with seat back braces and proper belt mounts. I have seen several 944 cars with poor sub belt mounts and right side lap belt mounts. Simple fender washers used on a belt eye are not enough for either belt. All mounts in locations where there is a single layer of sheet metal should have a doubler welded in and tied to other brace points before it should be used as as mount.

Just my 0.2c

Here is a seat installation guideline for the lower classes in Nascar. This is overkill but would be smart idea for driver saftey.

It is much more stringent in the upper classes. The seats alone are thousands of dollars and have 8-10 mounting points and are part of the cage.
