rear aluminum bulk head...are they worth it?

i see the huge benefit of having a front aluminum bulk head, but what about the rear? does it really need that much strength?

The failure point for me was were the rear turnbuckle screwed into the the rear bulks. In the stock bulks that screwhole would ripp out in a crash and then you were done. With aluminum bulks it holds up much better.
