Susp holder question xpro

[OneKiwi]

I been to the indoor track tonight and I broke 2 chassi plates and a shock mount and a shock stay.

I have an aluminum suspension holder at the front and the chassis plate broke off right there at the same place where they join... Now I know thathaving alu parts strengthens it up but also puts strain on other parts that might not have strain on in the first place... Is that my problem having the alu susp holder??

Im now thinking when I get new parts that I might just swap back to the plastic and see if it happens again.

Another Q where can I get a little wing to go on the front of the buggy??

Or whats a good way to weight the front down a little more?
