Is this straying off topic?....i understood you asking about the long term integrity of the frame, not the impact absorption, correct? If you are going to hit something, you want it to crumple and absorb as much energy as possible instead of directing that energy to the middle of the car, which is where you will be. If you want a rigid frame for other reasons, then i think it is a different topic, correct? You can buy mine if you want a relatively new one with tooooo much power.
