subframe bracket to differential broke!

Can anyone else speak to this issue, my bracket that is part of the subframe and mounts to the differential has snapped. Everything has dropped 2" and I heard huge bangs everytime I shifted last night. I don't beat on this car at all, it's a daily driver and I never even slam the clutch. (I know, shame on me). This looks like a very weak part, not sure how this could have been designed this way. It's even perforated from the factory it seems. Anyone else have this happen and what is the fix?? Thanks in advance

Yeah, it's kind of a thing...

Get a Unicorn Egg from M5_Jed. You might be able to save that frame, not sure. Regardless, re-enforce it with the plate linked in the pdf. The plate is actual size if you print out on 8.5x11 paper, and ~2.45 mm thick, beveled on the long edge...

Very common do a search and you will find a bunch of different solutions although most are how to prevent it from happening. I am sure they can be incorporated into a repair.

Your bracket can be repaired by anyone with a TIG welder. I worked on one a few weeks ago (not finished in the pic).
