Expected rear end shift?

[clemsonteg]

How much rear end shift can I expect when I air out? I will be installing a longer track bar and centering the rear end at ride height. I am a little concerned because it when I test fitted my rims this morning (20x8.5 5.5" bs) it looked like I only had around an inch between the inner wheel tub and the rim. I was going to run 255/40 tires all the way around, but that doesn't leave much room for the tires once aired out. I won't be slamming the truck on the ground, I'm not even installing a notch for now.

You can figure it out with a piece of string and a pen on the ground. Just draw an arch using the same length of your panhard bar and measure the lateral change over the amount of drop you have.

Thanks. I ran one numbers and it looks like it's 0.5-0.75" with around 6" of drop from ride height to aired out. I measured my rear end and I came up with about 57" from backing plate to backing plate. I thought that meant I had the wider rear end rear and I guess I expected more clearance between the wheel and the inner fender

I ran my extra long bar just slightly above parallel on the frame side. As it drops 6.5 inches the bar rests just under parallel and the tires are 1/8" difference from ride height. This pic makes the angle look more dramatic than iy really is....taken from the side. Looking straight on, it has a slight up hill climb.
