Came up with a solution for the weak front arms. These unfortunately won't be stronger then B4 front a-arms.. but they will be just as durable. Plus I can stock up on modified B4 front a-arms if B4 part of these a-arms break then I just transfer the custom lexan piece to the other a-arm and bolt them together. I don't think the lexan part will break its 3/8" So this is basically like having the parts availability of the B4 a-arms.. but pivot ball suspension. Perhaps I should have just started out with this idea instead of keeping it as my plan B.
I'm still trying to figure out an alternative for the rear a-arms but they might just have to stay 3D printed.. I think they might actually be durable enough as they are.
Here are the new front a-arms..
I will be going back to the track tomarrow.. I'm hoping that I will have much better results.
