I just had new tires installed on my 2006 GT so I had the alignment checked. The shop said the front right and rear right were just outside the acceptable limits. The shop also said the bad alignment could be due to a sagging strut. The car seems to ride fine to me and it's only has 75,000 miles (original shocks/struts). The car definitely passes the "bounce" test but I understand that isn't fool proof (see video below). What is the quality of the shocks/struts on an 06 GT? Would it be safe to say after 75,000 they need replacement?
