On the sweeper, my truck will lift the inside rear tire. When I let off, it wallows down onto the outside front tire and if I'm moving at a pretty good clip it will snap hook and roll over. That, plus my inability to tame the aggressiveness of the steering is why I am adding the roll bar. The sweeper kind of throws a curve ball at me. It needs a bit of a different set up than the rest of the track. Its shared by the oval racers at our track and tends to blue groove while the rest of the track doesn't. Traction is different in the turn and tires are howling. Folks that have watched my truck say that it is rolling a LOT in the sweeper. That would seem to explain the inside tire lifting. Correct me if I'm wrong in any of my assumptions.
