I have Ford performance handlingpack on my GT500. I just replaced the bushings at the rear swaybar. Quick question, eaven when I have tightened down the rear endlink with the two small screws the hardest I can you can still move the endlink quite easy. And when everything, including the bolt at the top of the endlink is tightened down they flex a few mm right and left when I pull it by hand. Is this normal or should there be no movement?
