-- Very clever! I love the low buck science in it. Most would have spent $$$ on a strain gage and datalogger - or even more on laser interferometry.
But you compared no bar witha triangulated bar, right? Did you make a comparison with a simple straight tie bar?
Also, what year car was it?

Randy, Bernd's test compared a simple single member strut brace with a triangulated strut brace. He used the Elephant Racing strut brace in both cases, and disconnected the triangulation member for the single-bar test.
The simple single-member brace yielded 3mm movement, the triangulated brace yielded 1mm.
The last time I discussed it with him, he had not performed the test on a car with no strut brace. In fact his setup used the main brace to hold the laser.
His car is an 80s Carrera.
