I recently installed Bilstein SLP shocks. The car is otherwise stock. The ride now is sustantially stiffer than stock. While the T Tops have made a knocking sound in the past, now it is worse than ever and incessant on both sides. The hatch now also occasionally squeaks when you go over bumps in addition to the other noises that come from the hatch area when the car is jolted. In the past I have tightedned the screws on the winshield side of the T Top opening which has sometimes helped a little. I tend to doubt that these screws are loose now. Has anybody made any inroads with this problem other than turning up the radio? Thanks.
