Another rear suspension idea, raising the rear trailing points Options

[bam914]

So there have been a few different ways people on here have raised their rear mounts. Here is my way. I will be able to adjust my roll center by shimming the pickup points on the mount. I will also be able to adjust camber separate of the roll center. I have a few more braces to make before it is all done.

Were it me, I would put the hiem joint attach points in double shear using a C section and tie in the supports at the same level of the pivot point.
Your present set up gives the applied forces a mechanical advantage over the structure intended to hold it. Overall, I like the concept but, as is, doubt it's integrity.
