Ladder bars uaually only work in one position. The bar must have a downward angle in relationship to the rockerpanel on the car. Put a protractor on the rocker panel and check the angle then put the protractor on the lower bar of the ladder bar. It should be about 2 degrees down from the rocker. start there with a loose shock setting. Good track tight shock setting bad track loose shock setting. I rarely adjust anything on the back of my car. the bars should not need any preload. The rear must be perfectly square in the car. You will need to check this closely. If the rear is not square it will act badly. Good Luck!!
