In any case, that you are testing your own product and publishing results is to be applauded.  |
Yes, we are going to test it if we have time. We want to compare. In hindsight, this probably should have been tested first but we're learning as we grow.

I doubt many other people have access to machines like this for play. We're fortunate in that a member of our group works at a large OEM supplying company and can (sometimes) go in during the weekend to test parts.

Shock loads are much more interesting to me than cyclic, but relatively small impulse loads. I want to know how everything will react when I'm hitting a steep berm at 100+mph, or the car is squatting during a compression event.

We are not testing the shear strength of the bolt, this is loading the LCA in a 4G bump scenario. This puts a bending load on the adjuster and the rod end, which is where these two pieces are weakest in loading. Much weaker then the threads from a lateral acceleration event.
This test is a shock load, at 3000 lbs of force.
