Think about the factory cars that do have STB's and have less then 5kg springs??? My old civic Si had them... not sure if they did anything but nevertheless why the hell would a manufacture put them in?? for looks?? HA. On top of that, they are thin as hell with small bars.... you want effective, weld a bar.... either way flex will happen to the weakest point wheather its on an appron (components of the strut tower), subframes, or chassis itself.
I'm not trying to rip on you, but.... but please consider the 'whole' and not talk so acutly.
I wouldn't say STBs are worthless, rather "not as effective" as it's intended for.
compairing a support structure engineer into car, with the rest of the car structuarly built off it is not quite the same as bolting on a pole after the fact.Not saying they dont help but your not compairing the same thing. There are most likely structual differences in the design of the front end of the car when a STB is included from the factory.
Aftermarket bars also have to be made to be able to accomidate for settling of the chassis, You note hinges on most. Factory bars are put on when everything is new and are solid, with no extra points to flex or give.
