More traction through lifbar travel or...

[Dirtmod13]

Was wondering if the liftbar helps give the car more traction partially due to the way it moves the jbar up and then the rear axle moves in relation to it. Any thoughts

It moves the rear to the right when the rear pinions up. I believe if you try to tune your 5th coil with that in mind, you will end up with the wrong spring rate for your engine, car, driver combination.
