Ormand said:Is that what he's saying? The way he said it, it means something entirely different. And a 7/8 bar mounted to the frame can provide almost any roll resistance, depending on all the other factors involved besides bar diameter. And when you use a statement like: it definitely says that you THINK you know what the factory wanted, better than they do. My guess is that the GM guys got exactly the rate the bar was "supposed" to give. Something about seeing all those race cars with GM design, like the Corvettes at LeMans, that makes me think they do a pretty good job.
He merely is saying if that exact bar was mounted to the frame, it would be the equivalent a 1.3" factory mounted bar.
"supposed to give" isn't saying GM didn't know what they are doing, he is just talking about what a 7/8" sway bar made to the dimensions of the factory sway bar is "supposed to give", when mounted like a sway bar should be mounted.
