When the LCA bushings wear out, your fav alignment shop will not be able to get your car into factory specs. The factory bushing is rubber that ages or wears out with heavy track duty. I wore the right front out on my CSS by driving at Kansas Speedway. The transition from the bus stop to the banking took it's toll. The Tarett bushings are a much more robust and better design, as is all their stuff.

If you've looked at the factory rear toe arms, toe is set by an eccentric (egg shaped) bolt / washer combo. When turning the bolt, it adjusts the toe in or out depending on where the egg shaped edge sits. Very easy to knock this system out of alignment. The Tarett toe arms use a turn buckle that is locked into place by two nuts. Much more robust.
