It also doesn't show that the strut towers were prevented from compressing, which would slacken the string. As for the speed at which you were able to take the turn, short of actually running the car through that turn repeatedly, with and without the strut tower bar until the car actually DID lose control and spin out, you can't say that the improvement wasn't simply due to improved driver confidence--you never actually proved when the limits of handling and adhesion were reached, with or without the bar.
With your experience, and with your demonstrable ability to find flaws in an experiment, I'm sure you know how easy it is for one to trick oneself into believing one's own hypotheses. Skepticism is a good response to that.
(don't get me wrong though--I'm still interested in getting a strut tower bar, not trying to *prove* you wrong on that, just showing skepticism).
I have no plans on desnorkeling my car because I don't see how it will add any benefit, but you're right, I have no idea whether or not to believe that it would detrimentally affect performance.

Hi,
I take your point(s). But, the String Test
did prove that the Towers did move on the same axis that the Brace occupied. Was there additional movement, maybe some, but minimal due to the undercarriage bracing and Radius Arms. The Towers tend to move perpendicular to the Fore/Aft axis of the Car (Side-to-Side) in response to Camber changes of the individual Struts as they respond to bumps and surface variations in the Road. Compressing of the Struts would not slacken the Strings as the Strut Mounting Studs are fixed.
So far as Handling is concerned, it's not truly necessary to run the Car to the point where it breaks loose, any threshold will do. The Road and Tight curve in question is 0.5 mi. down the street I live on - Mississippi River Blvd. This road is the 'Coast' Road along the East Bank of the River and so mimics the meandering of the River itself. I have driven this curve twice daily for a total of 29 years and the last 10 consistently. I know at what speed the Car's Rear End starts to get squirelly and raised this threshold by 7 & 12 MPH respectively by adding the Braces. These speeds would more than makeup for any Experimental error, at least to the point where one could definitely confirm that the Car could now go faster through this stretch. If anyone wants to start a collection for a few accelerometers, I could be more precise.
Defintely agree that proving a Hypothesis can lead to false results, but, while my
Data is not precise, nonetheless, the theory was proved...
Happy Motoring!... Jim'99
