Ok, now that you've actually stated your goal clearly, let's examine the situation. I agree that reducing weight behind the rear axle will reduce the pendulum effect. You are correct there. What you've done should reduce the pendulum effect. Congrats!
The problem in my eyes, is that the pendulum effect you are trying to reduce only happens AFTER the rear has lost traction and you begin to oversteer. Whether it happens in snow, or not, your traction has to be lost in order for what you've done to work. What I'm suggesting, would allow you to keep traction longer, and avoid overrsteering in the first place. You solution is a reaction to a problem. My suggestion, would prevent the problem from occurring in the first place, by aiding traction/grip in the rear.
From your earlier post:
"As shown in the chart to the right, the farther that weight gets from the centerline of the vehicle, the more the vehicle resists direction changes."
You've moved the weight (center of mass) forward, ever so slightly, which has made the vehicle more resistant to directional changes. That's not helping your handling. That's what everyone here has been saying. They're not just 'jumping in on my thoughts', they understand the science behind it.
I'll repeat myself from earlier. It's your truck. IF you're happy with it, then just be happy. Who cares what math and science say? But, beware the placebo effect that modding can have. Many times, we think all of our hard work has made an improvement when it actually hasn't.
Finally, I'm not just standing on the sidelines here. You can see my truck. It's designed primarily for handling/grip. If you want to see what my 'crazy theory of weight distribution' does for handling lets go autocross sometime. My blown 3.0 against your blown 4.0. I'll even put some sandbags or something behind the rear axle.
Jeez are you a piece of work and a PIA. You are wrong again! I never wrote that center of mass is not the biggest concern in handling of a truck. Ya it's heavy in the front, we all know that, Mr. Obvious. You are stuck on that one variable. It is probably one of the largest variables in handling of a truck. But that has very little to do with reducing the polar moment of inertia and that force is there regardless of weather the tires break traction or not!
I would gladly take you after I am done working on it and make you look like a fool, spun-out with two hundred pounds of sand at the tailgate!

You are not making sense and called me out here based on your misunderstanding.


I'd rather you bow-out of this thread, but instead, I am going to. The thread is all screwed-up now and focused on one thing that you sir have got wrong!

I got a gain in handling/cornering by reducing the polar moment of angular inertia at the rear of my truck. A concept which is explained by the laws of physics and many others practical experience. I followed the laws and their lead.
