im also running aluminum servo tray posts, belive it or not it does make the chassis even more ridgid.
i broke down and bought the aluminum stuff because when i bump started, i could see and feel the chassis flex a little, right by the engine, and i was worried about breaking my new engine and clutch, now its like trying to flex a piece of iron.
do you have a one piece engine mount? if not i would highly recommend one. if you have a picco or picco based engine it might be hard to find a one piece mount cheap because they have to have their own special mount because they have a weird crank case.
