I am not the first to do this I'm sure...

There are people running 8's and 9's on the factory TII rear. You think they did that with the Mazda mount? No way...

To break the mounting tab off the sub-frame there would have to be slop and movement in the drivetrain. I will have as close to zero slack in the drive train as physically possible with the stock drivetrain. IF the mountuing tab did ever break, which i doubt. I will beef that up also.

I did this years ago, it worked, but like mentioned above I ripped the mounts off the sub-frame, I beefed that up with some angle, been good for 2 years. But with a pinion snubber, you shouldn't have wheel hop... What are your tire pressures, and suspension set up?
