Ever since a while back (after the Eibachs) I noticed that my front left sits lower than the right. I can't even get a floor jack underneath! It is 1/4" lower (or the other side taller?). I measure fender gap and floor-to-fin. All the bushings look good, stock tire height and equal pressure, insulators okay, never wrecked (but driven hard), and nothing loading it down inside. What could cause this?
