You must not have had it welded in right cos I have Autocrossed my car a few times like a nut and not had issues with the upgraded brackets.
You might want to try welding a small vertical piece of metal to the rear of the backing plate to weld up onto the subframe to make it even stronger. Make sure the bushings are well greased and you're not tightening the bejesus out of the bolts, effectiviely not allowing the bar to rotate freely.
