 ```Message text written by INTERNET:rgb@exact.com >I hate to argue the point, but the rear trailing arm hinge line should be the same on both sides. I've seen several references to using this to adjust chamber while sitting. What you're really doing is changing the caster/camber/toe-in.. don't believe you want different behaviour on each side. JK Jackson did alot of research into using this to enhance handling for Autocross, but never to adjust camber.< I agree, due to the angle of the trailing arm. A hinge change will alter toe-in, and to an even lesser degree (AFAICT) caster. Most likely, the caster change will not be significant, but who can tell? It is clearly superior to find the cause of the malaligment and fix it rather than patch it. However it may be impossible to find/fix the underlying problem, but it ought to tried. If the repair fails for whatever reason, then it is better to patch the problem rather than leave a major difference side-to-side. First, using a spacer one could try to raise ride height, and this will induce more positive camber slightly. If I remember the original problem, the sagging side had more positive camber (seems counter-intuitive, but I THINK that was the problem as stated.) Now that ride height is about right, then correct the camber with the brackets. Kastner even talks about filling and re-drilling the brackets to suit the application. When the camber is about right, then adjust toe-in with shims and re-check the camber. HOpefully it is close enough to symmetrical. How close is close enough? I guess +/- 0.25 degree? The range of cambers is usually about a half degree, then I think the symmetry ought to be within half of that half degree.... Same goes for the toe-in. WHile I agree in principle with your position that the hardware OUGHT to be symmetrical on each side, it is not necessarily bad that the trailing arm mountings are not symmetrical. ASSUMING the trailing arms themselves are symmetrical, since we are placing the trailing arms in the exact same positions (mirror image) with all the hardware relative to each other, then they ought to track the way we intend. I don't think it makes all that much difference to the car exactly what brackets and shim arrangement it takes to get this alignment. It does make a difference to some degree if the tire loading (weight on the tire) is significantly different due to frame bending! -Tony caster, but remem ```
