It sure did do it wrong the first time and nobody here told me so. Did you also notice that I mentioned that we bent the beam in that spot 3 races in a row (3 new beams) till we decided to look at the way we were doing it? We can't do it now but I would have skipped that bar all together and put the a-pillar ontop of the heater channel with a reinforcement plate welded on to distribute the load onto the channel. This is also where I would connect the lower beam support tube.

Sounds to me like you would have rather built more of a disposable, light weight, short course car?
I understand the benefit of saving weight, but I also believe that to build a car that will last, and be durable, you really shouldn't cut too many corners. I'm pretty set in my design of joining the front beam to the rear torsion housing with two stout pieces of .120 . In my mind, that's the foundation of the entire chassis, and with that foundation in place, I can utilize lighter tubing in places that some builders wouldn't use it. The way you described might save some weight, but I just envision tearing the body to pieces by relying on it as a structural chassis member.
I guess this is the reason I love off road racing so much. It's still possible to build a car of your own design, in your own garage, and go race it against the best in the class. If you get it wrong, you can always go back to the drawing board, but if you do something out of the box, and get it right, you just changed the game. This will be the second tube chassis build for me, so it's safe to say I learned a lot from the first build. It's also safe to say that I'll learn a lot from this build.
With all due respect, I don't want to just build a Daveco replica...
We know his cars can win races, I want to find out if my car can win races.
