Take some pictures and post them. Focus around where the sway bars attach on the ends for both front and back. The fronts mount to the struts and the rear to the lower control arm. Generally in those areas you will see the most common mods such as bushings, control arms, etc. Also one of the vendors recently posted some illustrations of the Gen5 suspension. You those as a guide to locate where mods may have been installed.
