Somebody posted a picture of the RPM arms that had broken a couple of weeks back. I've never seen or heard of anyone busting a stock one.
that was me who broke the arm...
The stock a arms dont break, the just bend/bow
The rpm arms can bend... with some nast hits, which I am fully capable of
they seem to ben at the inner hinge pin if the do bend at all. the a arm I broke got bent from casing and hooking the jump with the rear a arm, it bent, i heated it up and bent it back, then it broke hitting a steel upright i-beam.
all in all the rpm arms are stiffer and perform better imo.
