I've been comments the past few months about the rear height of my XJS. I replaced all shocks about 6 yrs ago with KYB Gas-Adjusts. Because the "*** in the air" comments finally bugged me enough, I have researched and find it's not an optical illusion. The shocks continue to be in good shape, i.e. no bounce when pushing on bumpers. A buddy suggested the shocks are the source because they are the wrong application. He asked if coupes are heavier than convertibles. If yes, then the KYB's might be for a coupe and KYB doesn't recognize the weight difference between the two models. Imput/comments/help?
