Are you landing on your wheels? Shock towers usually break cause the shocks are set to not allow any dampening...a ST needs to bottom out on jumps or else it transfers the stress to the easiest place to break..usually shock towers....if your st doesn't hit the chassis on jumps your setup is wrong and no matter what shock tower you run you'll continue to break something...add a aluminum shock tower and you'll break the shocks or control arms off...it's all a matter of setup...try running a way softer shock setup let that chassis hit the ground it's why it's there...there was someone here who owned a Jato and broke shock towers like mad he was proud to say though that his Jato never bottomed out....but too stupid to realise his setup was breaking his shock towers not anything else.
