Tearing rear anti-sway mounts.

I have the big 28mm rear bar and I've torn through two different mounts. Any suggestions?

Find stiffer rear springs or find a smaller rear bar? 28mm is pretty beefy, you are going to need a high spring rate to go with those, should take some of the pressure/work from the bar/mounts if the springs arent traveling as much..

28mm is 200%+ more stiff than the stock bar, maybe try finding a 25mm rear sway bar as a compromise?

yeah if breaking the LCR's, id recomend getting those reinforced or getting the SVT style ones that already were. Big bars have been known to destroy those arms where the endlinks mount.

The mounts on the cradle? I've never heard of that, before.

If thats the case, I'd use a thicker gauge matrial, for the bar mounts that are on the cradle.

You have bind in the system. I noticed the same thing and I have the same bar as you. My friend Kendt ripped the sway bar mounts off his rear subframe. The most important thing to know is this:

Quote:
To be honest we discovered (upon re-installation of the RSB) there was nothing wrong with the stock mount. The clamps that go over the center poly bushings were causing the bar to bind. Once tightened, the bar could not be rotated AT ALL so we knew that was the issue causing the stock mounts to be ripped apart. We added a spacer when we re-installed everything and it was fine.
This was one of those cases where I could see the fix in my head almost instantly. I love it when that happens.

First thing I did (not pictured) was put the bushing on the bar. Gripping it as tightly as I could, it was not to close the bushing all the way. This means that if I tighten the bushing on the bar and there is no gap, then it is likely going to be too tight.

Here is the problem:







Notice how the bushing sits proud of the bracket? When the bracket is tightened against the mount, it compresses the bushing too far.

So, as you can see above, I cut some fender washers to work as spacers:





That makes up the gap nicely. The flat edge ensures that I give up no adjustment and the spacers won't hurt the bushing. Next step is Super Glue the spacers to the sway bar mount. Since all I need is for the spacers to be help in place while I mount them, Super Glue does the job. I have found that a quick dab to hold washers or spacers in place can make "how many things do I have to thread on this one bolt" kind of jobs a lot easier.





And now the bushing on and clamped down:



Hard to see because it black, but there is still a little gap in the bushing like I believe there needs to be.

Looks like they made the sway bar brackets a little smaller, then they should be. Funny my brackets don't look like those. Just to add, you'd feel the resetense in the bar as you'd rotate it, to mount the end links. And to add a little of the special grease.
