I've tried a popular brand of crossmember with a tubular design in my car with a 4 speed. It was made of chrome-moly and has a couple less bends than yours but the diameter looks about the same. Driving down the road the shifter handle would move up and down in a bouncing motion at least a 1/4 inch. That was too much for me. I took it out and bought a G force unit. Problem fixed. It would be nice to be able to measure the flex in a operating condition to tell how strong the piece is.
