IMPORTANT The mounting bolt (19) is centered in the oblong hole by the adjusting rings (arrows). By inserting the adjusting rings the mounting bolt (19) can be installed in the right or left position, which adjusts the wishbones by 3 mm inwards or outwards.

IMPORTANT

Do not tighten the hexagon nut yet so that the wishbone rubber mounts can rotate when the suspension deflects.
