My thinking is a broken collar bone is better than going face on into the steering wheel or unwrapping and going through the windscreen.
If anyone has a solid safe and reasonably achievable modification to a stock car to improve this I am all ears.

Speaking of broken collar bone, i think that according to pic from
TP-210-9b.pdf doc, the angle from top of the seat and top rear car point should be in "Acceptable Range" area, withing 40 deg shown...
by the way, the angle is about what you see on my 1st picture, it might be a 5 deg more, my guess it wound be around 25-30 deg TOTAL, if counting from the top of the seat/horizon line...
withing 40 deg shown .... I will check it this weekend....

This is Great Idea!, but do you think this hole will make b-pillar weaker, beside this b-pillar might not design to handle so much force while front impact. We might need '69 b-pillars welded in...
Just my thoughts...
I love to hear from guys who has 911, perhaps late'68 or '69, where those Factory mount 1st installed... if you guys have pics, similar to this, please...
