Shims are used to adjust the height of the outer spherical bearing tie-rod, and the bumpsteer is remeasured until the curve is optimized. Ideally, bumpsteer should be as close to zero as possible through the working range of the front suspension. Slight amounts of toe-out under compression are preferable to any amount of toe-in. Toe changes should be kept to a maximum of 0.010-0.015-inch through the first couple of inches of suspension travel in compression or rebound, preferably only in the direction of toe-out.
