That cage looks very well tucked away and probably would not be too much of a hazard. Though it is very hard to tell how the body will stretch and contort in an accident. For myself i determined that even with seats positioned on the floor the S30 chassis is just not big enough to put a cage far enough away from the head of a 6 foot tall guy. Though I will say that I feel head butting a 1.5" dia tube with cage padding or head butting stock sheet metal is probably not all that different, as far as PSI. But thats like, my opinion, man.
