Yep, both of my brackets broke (actually tore!). Came apart at the spot were the sheetmetal makes the right angle turn back towards the bushing. The reinforcing plates won't fix this problem by themselves. I had to fabricate new brackets. Got some angle iron from work and cut it down to fit and welded it to the subframe. I then used Stazi's reinforcing plates and welded them in also. Now with the new parts and the huge Prothane bushing brackets, I think it will take a major screwup to break anything. If you start hearing a clunking from the backend, get under there and check the sway bar mounts carefully. It may just be the front end pulling out of the slot or it could be total sheetmetal failure as in my case!
