Broke my third rear shock tower last night in two weeks. Replacing the tower isn't the bad thing it is that the stupid esc wires go thru it. It was on a big track with big jumps, might go to aluminum or try out JC wing mount. I didn't see it break but there was big jump that I couldn't down side with out wiping out half the time so I would over jump it and land on the flat with some chassis slap and I think that's what finished it off. I don't want to go to aluminum but I might but than is ill probably break a U brace, lol.
