I'm almost certain you've got that backwards. The way I read Brian's setup, the lower shock mounting position is in the hole closest to the wheel, which would have the most limiting affect on actual steering throw.
I realize we all have different driving styles, but even with my shocks all the way out on the arms, there's no possible way I could ever use that much steering. The car turns so hard and so sharp that I find myself constantly turning it down. In fact, the smoother I get, the less steering I seem to need. I'm not racing mod though, only stock and 19T, so it's probably different if you're running mod.
I know Brian uses the Parma tires and sauces all the way out to the hard stuff. On Parma, that's all but like .5 inches of an outside ring. Parma is, without question, my most beloved tire on carpet.
