Hey PQ, this sucks to see, but also very educational.
What setting did you have the rear bar set to (meaning which hole are the endlinks attached to)? I think the stronger rear bar coupled with your supercharger has caused the rear endlink brackets to fail the way they did. Too many hard launches and the weakest part of the whole rear endlink set up failed, which happens to be the control arm bracket. The other side is starting to crack too.
Might as well get a set of these:
