I noticed that the adjustment bolts on the IE kit are always at 90 degrees to the support brackets regardless of where it is positioned. It seems that with any kind of adjustment on camber / toe-in (except at original hole location), the centerline of the two bolts on each trailing arm would not coincide. Has anyone had any problems with premature wear on the trailing arm bushings because of this ........ or does the urethane bushing accommodate the misalignment?
