It is bottoming out and it was before I even put this setup on the car. If you look close at the second picture, my inside rear is slightly off the ground. Ths only happens on high speed sharp turns. Denny supplies a 1" solid sway bar, the Hotchkis bar I used to run was 1.5" hollow. Using the Addco online sway bar stiffness calculator, there's a significant stiffness difference between the two. A member here, @bjkadron volunteered to help me do some mathing once I get him some weights for him. I'm going to make a splined end tubing type sway bar and I want to make sure I pick the right size tubing. Had he not volunteered, I would have just gone with the same size tubing the Hotchkis bar has, 1.5" x .188" wall. I may end up with that, but at least I'll have some math behind it instead of just guessing.
