On a 2 link B-mod rear suspension with the springs centered on rear end, running Left bar up around 26 degrees (Right side around 8 degrees). The LR hikes up and drives the tire into the track for mechanical traction. At the same time, this steep angle causes the rear end to steer noticeably. The first effect tightens the car while the second effect loosens the car. It's happening at the same time, so which effect is more dominant? The chain can limit the amount of hike, so generally when would you allow max LR tire drop and when would you tone it down? Thx!

Initially, you get more lift vs steer. At some point, this effect reverses. It would be at 45 degrees if you ignore axle housing rotation.
