About cranking t-bars part not affecting ride I say bullsh*t! It is simply not true that cranking them does'nt have any effect on spring movement/stiffness. If you have a coil spring and you force the coils closer together with a spacer (or in the case of motorcycle or high end racing shocks/springs, an adjuster) you make a significant difference in the length and stiffness of the spring. That is called a preload adjustment in the racing and motorcycle world. You use an adjustment like that to reduce the amount of possible motion in the spring, it will help compensate for more weight and provide just the right amount of travel in the spring. When you crank the torsion bars you are doing exactly the same thing, if they had 90* of total motion available in the up direction (oversimplification I know) and you crank them 5* they now have 85* available and as with any progressive spring and even most "linear" ones the force required to deflect the spring a given angle/distance will increase towards the limits of the spring's travel. You are using up the initial travel "soft" zone when you crank them and they get very frikking stiff. I have cranked t-bars, with ultra low pro bumpstops, and some 33" tires with very low pressure to soak up road bumps, and it rides like a hay wagon. I have some brand new bilsteins on it too, no improvement. My A-arms are NOT smacking against my bumpstops, as evidenced by the dirt buildup on the stops unless I am wheeling it. The whole concept that you don't change the behavior of the spring by using up some of it's travel is ludicrous. Like some of the other guys said try some real world comparisons, go crank some an inch and tool down a familiar stretch of asphalt, you'll find a bunch of seams you didn't know existed I promise.
