I was fooling around the other day doing some freeway runs with my friend when I suddenly broke my diff mount again. Its been the third one I break, one was the original and the others were the mazdatrix comp one's. My question is What could be causing it to break??? First my tuner said that I had too much wheelhop being caused by my worn out suspension. I guess it made sense but he said that it should be fine as long as Im not shifting hard the first couple of gears. Now the thing is that this last time I broke it I was going about 90something(shifted to 4th)and I just heard and felt it snap. Any ideas. And by the way, I have about 280rwhp. whats going to happen when I go for the numbers I want. I need to fix this, I cant afford to be replacing the same mount over and over.

yeah
I have a brutal clutch, wide sticky tires and my diff mount isn't broken.

owen is fat

box it in by welding small slabs of metal to it to make it a solid diff mount.

reinforce the subframe by welding on a small plate where the mount bolts up and also add gussetts or triangulate the subframe mount to the subframe.

adding a pinion snubber is a good idea too.
