FRONT ROLL CENTRE SETTING and STEERING 12
Front roll centre height can be changed by moving the spacer relative to the wishbone spherical
joint.
When you change to ´low roll centre´ configuration the push-rod length has to be shortened by 1.2
register turns (
≈
7 faces of the adjuster) to put the car back at the same front ride height.
When adjusting the roll centre height camber gain versus wheel travel varies a little.
