I was just stating that doing this experiment on a 914, but test the flex at the rear pickup point instead of the front would be interesting.

The thing to think about on a street car is that you start eliminating the crumple zones by stitching and adding metal to everything. If you get his that energy has to go somewhere. I do have a inner long kit in mine and I like it a lot. I got it too hot when I put it in and bent the tub. It was a puckering experience to get it back straight.

Yes... it makes the car stiffer. But it was designed with the spot welds so the front and rear of the car crumple in a predictable fashion, absorbing energy from the crash. If you weld up all the seams, then YOU become the item that absorbs that energy.


Watch an Indy car or F1 race and notice how much stuff flies off the car during a wreck. Each part it sheds is energy that is not going into the safety cell or into the driver. Today, drivers regularly walk away from wrecks that would have killed them 30 years ago.

So think very carefully on how much energy you are willing to absorb when you get hit before breaking out the welder and welding up the seams.
