Ride height

As post 13;plus
The whole point of the measuring is to get an imaginary line drawn through the centers of the LCA pivot points, to be parallel to the floor. The pivot points are; the center of the LCA inner bushing, and the center of the ball in the BJ.When this line is parallel to the floor, your front geometry will have the least amount of camber-change as the suspension cycles up and down. This translates to the toe-in remaining stable, and then the car theoretically should be free from wander due to toe-change. This window is about, or can be about, 2 inches high so there is a bit of wiggle-room in setting the ride height.The factory adjustment gives you an easy way of achieving this parallelism. It is also important that the rear ride height is the same left to right, otherwise the front will have to be preloaded on one side to compensate.So if you have weak spring back there, now is the time to take care of that.
