for those who think the stb is just cosmetic.

I'm not sure what this proves, really. If you're trying to say it proves the sides of the car crush slightly and the stb prevents that, your missing the big picture.
If that string has slack in it, it means one of three things:
1) The car sides have crushed inwards...permanently.
2) The string has stretched.
3) The string mounts were not stable.
Number 3 is most likely, although I'll give possible credit to number 2. However, if number 1 is correct, then the car is permanently misshapen by something as simple as a hard drive, and it's time to take the car back for a refund.
My point is the only way you can tell if the stb COULD do its intended job (but not necessarily if it actually DOES the job) is if you saw the string go slack while the car was in motion. The moment you stop the slack should disappear, or you have one of the three cases listed above.

How about tying the string and then jacking up the front side of the car and then place a few stacked 2x12's under one tire... gently lower the vehicle so that the suspenion is compressed on one side... then see if there is slack in the string... jack car back up and see if the slack is taken back up

ccarnel's experiment is better, but it doesn't test dynamic loading...in that case, you would need to drop the car quickly to see what "extra" pressure the suspension might encounter during hard cornering or large bumps. Either way, it's still a more valid experiment than the original suggestion.

I think what UFeniZe is suggesting is that his experiment shows that a string that was taut prior to enthusiastic driving has become less taut afterwards.
If that is the observation being made, and if the string mounts were stable, then there is support for possibility number 2 mentioned by MacGyver, that while being driven, the 2 points that the string was attached to flexed APART momentarily, stretching the string. The flexing of the car, however, would not be permanent, or else the string would still be taut when the car returned to a static state.
Someone who has some kind of strain gauge should be able to prove/disprove/quantify any inward/outward flex. Please?

those that think because they don't 'feel' the change due to a mod (whether it be thermocoating a header or installing a strut bar) are sorely mistaken. it's really no use to argue about it because it's like trying to make an NA faithful turn into an FI junkie.
