There are 8 screws and the shock tower reinforcing that so called stifness.
Try what you will.. do what u may.. if all your friends jumped off a bridge would you ? The only difference is now you have to take out all those screws to change your spur gear. If they want flexibility .. use fiberglas!
And I would never stress my chassis like you are suggesting. Perhaps you should all be using a TA05Rifs instead of a 416. And for some reason, I dont think that gal on the left is wearing any panties!
