All you're doing is moving the flex point from the firewall to a different part of the chassis. The flex and fatigue still occurs, albeit less noticeable to the driver since NVH is presumably reduced in the cabin. Like I said, this additional chassis flex certainly doesn't make the suspension work any better, and can't be better for the chassis itself. Explain to me what I'm missing here, because the only positive thing I see from these is a quieter ride.
