adjustable trailing arms aren't a necessity. what they allow you to do is center the rear front to back in the fendewell and correct the thrust angle of the rear. thrust angle is the rear point left/right of straight ahead. ever see a car where the rear of it was off to the side of the front end while driving down the road?

this one shows a negative thrust angle, or pointed to the left.


this one shows a positive thrust angle, or pointed to the right.

TRAILING ARMS - Some call them rear LCAs. These also help to keep the rear from rotating upward. Stock are stamped steel flimsy things. Some come with spherical rod ends. While this may be the best way to go as there is no rubber type mounts to flex from, they transfer all noises as they are metal. Also, over time, using the spherical rod ends on the street will wear out relatively quick due to dirt and such getting in them. Some are adjustable. What this does is help you to make sure the rear is pointed straight with the centerline of the car. If the rear is point left/right, the car will dog leg to that direction.
