Finally snapped the front diff bolt on my euro m3 210mm diff. Im wondering if the AA diff support brace or the max psi weld on brace will work for me? Or just upgrading to stiffer bushings and a grade 12.9 bolt would cut it?
AA brace should do the trick. It's designed to stop the diff twisting which I believe is what causes that bolt to snap. I made my own version of the brace and seems to be working well so far holding things together.
Got poly AKG bushings for subframe and diff and replacing the snapped bolt with this larger grade 12.9 M14x1.5x80 bolt. Hopefully that holds

Hopefully this M14 grade 12.9 bolt holds up with the new bushings
