Some people have said it has broken the "re-bent" stock bushing bracket.
I don't know if this was the old or new style brackets though.
Also Aussie has fabricated a set of new brackets that will work just fine.
I used the ones supplied with the pro-thane bushings (from the original run last spring/summer) and they are holding up just fine even with my constant abuse... They only took a little modification to fit.
