you have to adjust the length of the endlinks with both front or rear tires on the ground (or ramp) so that they are absolutely free from any torsion flex from the swaybar when installed. otherwise your swaybar has preload and works against your coilovers or damper set causing the car to tilt or give false corner weights.

if you have adjustable sway bars you can use the intermediate settings with one endlink longer than the other side, etc. it's pretty cool. i haven't seen the whiteline one for the z in person.
