Z height is correct, no clue where they came up with that. It is defined as the vertical distance between the lower, most inboard point, of the steering knuckle to the center of the lower control arm pivot bolt. Most easily arrived at by subtracting the knuckle to ground measurement from the pivot bolt to ground measurement. Vehicle must be on a level surface front to rear, and side to side when taking measurements. Bouncing the front end up and down between measurements helps to get an accurate reading. I set them at the max height, which for yours is 5". Reason is the bar will naturally lose tension over time, and the dimension will decrease. Once it is adjusted and the alignment is done, messing with the bars, (even a little bit) will affect the alignment substantially.





The adjuster bolts usually vary. The strength of the bars, and vehicle load distribution varies. It's rare to find both bolts threaded the same distance. Getting the ride height in spec is what you're concerned with. Don't pay much attention to where the bolts are.


If you really want to get accurate, adjust them with 1/2 tank of fuel and load the vehicle how it is normally driven, passengers and all! If you could watch the alignment angles change on the alignment computer, with and without a driver, you'd be amazed. A large person in any location in the vehicle can throw it out of spec! I've done many alignments where I had to gently ask the customer to sit in the vehicle when making the adjustments.
