I race a ladder bar car. my car is set up with 2 degree down angle on the ladder bar with 2 degrees of down pinion angle. It will not work at all if the bars are past level or running up hill in the front. All measurements are taken in relation to the frame or rocker panel. if the car is set up correctly no preload is best. my car is 3140# and i have a 110 lb spring rate on the shocks. Typically the bolt holes are too coarse of an adjustment. I use ride height if i need to make any adjustments. Start with the shocks loose on the front and rear and the tighten as you test.
