Frame Mods to Type 65 Coupe

[Hankl]

I noticed that you did not angle the top bar out like Hank L did on his blog. Will this still have you pass NASA rules to run in what ever class you are going to run?? I hate to see you do all that work and not pass tech because you did not angle the top cage bar out..

As Jake said, the rules don't say either way what the angles of the bars should be, we just adhere to the structural necessities of the structure. That cage should pass any sanctioning bodies rules.

From the clip of the rules posted it looks like there is no height specified of the door bars. Is that the case? How do you determine how high they must be?

Todd,

What we were told, is that the preference of the sanctioning bodies was that the bars cover at least 2/3's of the door opening, that in of itself leaves some room for interpretation. The way we worked it out, was to take a measurement of the door opening, not from the sill bar, but from the lower frame rail. From the frame rail to the top of the forward bulkhead is approxmatly 16 1/2", 2/3's of that is 11". We measured several cars that were in the area, and found that most bumpers started at anywhere from 12" to 20", and terminated at 16" to 26" in height(From Hondas to 4x4 Ford Expeditions). With a ground clearance of 4", 4" of distance from the bottom of the 4" tube to the top of the frame rail, and then 11" upwards from there we reached 19" for the top of the upper SIB (Side Intrusion Bar). Any higher, and it starts to become problematic for entry and exit. We moved the top bar outward to negate some of the entry/exit problem, as it ends up providing a little more room to the driver to pivot their body into to the car as they slide in.

Hank,
Cant wait to see the treatment of the bars with the doors. That should be quite interesting.

Jacob,
Your mods are very interesting as well.
