That's an expensive way to prevent it from happening again. You could just practice a lot to prevent doing your end over end tumbles lol.
I never had any problems with my posts on my gmaxx or supermaxx.

I do e-o-es because I like to. I have broken many shock towers and bent many shocks. I have been running RPM shock towers, but I finally ordered FLM towers last night since I won't be breaking them any more (barring a strong crash to the a-arm). I love this cage, and I only bash this thing (and I really bash it). I am going to MMM next week, so I'll really be crashing it now. WooHoo!
