You need to align the axle so that the panhard-to-axle bolt is directly above the left side frame rail and leave it there. Moving that around changes the characteristic of the car too much throughout the entire corner. It may alleviate your problem on entry, but cause the car to do something else on exit. Put the bolt connecting the panhard bar to the chassis along the centerline of the axle at ride height (make certain the driver is in the car). Then go to work adjusting the car with bars, shocks, wheel spacing, and ride heights.
