And why would you want to do that? Disregard the fact that the suspension is unloaded, hanging down, and out of spec. What would you hope to gain by preloading the bar more? Strut towers with stress cracks? Camber impact? Don't really see what you're getting at. Keep in mind that preload is kind of a touchy topic. Some agrue that minor preload is needed on tower bars, some that none is needed, and still others argue that tower bars aren't needed altogether. I've yet to see anyone yet however argue that a ton of preload is desirable. You just want to kick out some slop, not stress suspension components.
