hi!
first thanks for your last help!
I bought all the necessary to convert my ST into the ATX buggy and it is wonderful, but I have a lot of friends with monster and many times we race in "hard conditions", so I bought new tires to convert my ST into MT... the main difference (in my model) between the ATX and the MT is the front shock tower (FF040) (I have installed the 2 speed transmission of the MT) which allows only to install the ATX body (I think) so here my question: If I leave this piece installed and I switch only the body mount, will I have any problems (stability, rigidity...) while using the MT version?

thanks!

The only thing with leaving that shock tower on, is that you will have fewer shock mounting options. If this is not a problem for you then there is no real reason to change it. Hope this helps.

I think it is not a problem and in that way I can change more quickly my model!
thanks a lot for your reply!
