Pre-Load on Ladder Bar
Doing some reading.

One says start at neutral, then adjust passenger side bar upward, then raise car to where you can insert the bolt.

Another says start at neutral, then adjust passenger side bar downward, then lift bar to where you can insert bolt.

Maybe this should be a poll?

Edit:

Then I go to Morgan's book and he says you drop the driver side bar downward, then lift it back to insert the bolt.

What are the corner weights with you in the car and the bars neutral?

Op, you can achieve positive pre-load from either the driver, or passenger bar.

Lower the bar driver side

Raise the bar passenger side

I presume, this is what the person you're reading, meant to say OP.

If you have one going right (low horsepower anything below 1000-1100 HP), as a last case scenario, positive pre-load can fix it to go straight, out of the gate.

Another better adjustment to fix one going right is to run the rebound adjuster a couple clicks tighter on the driver side, and the compression the same, a couple tighter on the passenger.

You can also run the rebound looser on the passenger front damper, in conjunction with the staggered adjustments on the rear, mentioned above.

Putting the rear end in a bind - pre-load, is a last resort.

Neutral with the driver side bar, adjust passenger side bar to pull end down 1 hole diameter to install bolt.

If I remember right that was about what it took on my Camaro to launch straight with wheels in the air.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

On level ground remove right side bolts, jack right front up to match left front travel and install bolts. Works every time!

You may want to look at corner weights and ride height on all four corners. Alot of time I will shim the lf coil or raise lf coil over depending on set up to get ride height close with driver in seat. That puts weight back on rr tire and the usually very litle preload is needed.
