I still cant grasp why it wouldn't increase spring rate in a straight line when the cars suspension is compressed. I can't explain it in words but I can elaborate with a sway bar in my hands or showing someone what I see as happening when the suspension moves. If the bar is connected to the LCAs and the LCAs move up equally on both sides then what happens to the bar? Wouldnt it have to flex somewhere which would be equal if it did. And that flex is tension pushing the LCA back towards a rested state of the swaybar where it is not acted on? Damn my racing thoughts that I cannot figure out or get a grasp on. I completely understand it in a turn but not so much a straight line.
