Man what did I say about this kit????

Didn't notice the tubing used for the frame connector is bent. Also didn't realize the plate for your roll cage is not part of the connector.

Here is something to think about. A straight peice of alluminum tubing. You can walk around and push ceiling tiles out of position and even slide boxes off the top shelf with it. Now take it and put the slightest bend in the tubing. Go back and try to do the things you tried before. You can't the bend just get's worse.

Tubing is bent all the time in race cars. But, if you notice there is a supporting structure welded in to support that bend.

Omg dude you totally called it

Yes, let's look at your analogy. Pushing ceiling tiles out of position takes almost no effort. Your piece of aluminum tubing with a slight bend in it is going to need to be paper thin for it to bend oppose to moving a ceiling tile. Assuming you're not using a paper thin aluminum pipe, the pipe even with a large bend in it will be much stronger than the force it takes to move the ceiling tile. This is exactely why your anology doesn't work. A 1.625 .120 wall pipe with a slight bend in it is a lot stronger than the sheet metal it's bolted to. The 1.625 .120 pipe will be the last thing to fail.

Nobody is talking abgout failure, we are talking good design practices, common thinking is any member that changes direction needs to be supported/braced/triangulated at the bend. If not, bending will be significantly easier, however slight. We should always be trying to achieve the greatest stiffness with the least/lightest design, anything else is a compromise. KISS Memo applies here I think,

His analogy was only a generalization for visualization purposes, wasn't likely meant to prove or disprove anything.
