Many times you must shim the endlinks with your weight in driverseat as the body maybe tweeked..........springs,etc.
The nice thing is the way the bar attaches to lower control arm is that the ratio is 1:4 so even an inch of asymmetry only needs 1/4" of bar correction.
Or are you mystified by the front bar's angle thru the mounts to prevent the use of hard urethane bushings. Remember the front bar is already stiff enough for the tires and weight even with lowering springs. A stiffer front bar needs much stronger tires to avoid the added understeer tire wash out [exceeding the slip angle optimum of 6 degrees at 0.8G]
You need a pit/drive on ramp that is level to finely trim sway bars or a tiny person to slide under and fine tune.
The Q 146/123 springs mean that the body depresses a lot with weight depending upon the weigh location.
Just as 22.5 gallons or the lack thereof moves the rear 140/246= 0.57"
A driver or not [at the C of G plus offset] changes the leftside the same amount at just 150 pounds, a big guy ~~1"
