Eibach 12 Porsche 911 Carrera 997 Anti Roll Kit (Manual Trans Only) Introduction to StoryBoard Pro on Vimeo. Sway bar stabilizer end links connect the sway bar to a fixed point on the suspension and are designed to transfer forces between the suspension and the sway bar. Adjustable end links are an upgrade over standard, non adjustable end links that allow for the removal of potential sway bar interference and preload on vehicles with lower ride heights. Removing sway bar preload allows quick adjustment on bars with multiple settings. A properly set up sway bar leads to less body roll and thus, improved handling.
