RE: New chassis brace from ARO Products?
As far as the brake servo flexing the chassis I suppose that the little bit of flex involved is better than a burnt out servo. You could also bolt a piece of aluminum to the chassis where the batt box goes to replace some of the support lost when you removed the batt box. You could also incorporate some form of fuel tank mounting setup to mount the extra tank to in the piece you bolt to the chassis. I am assuming that you are still using 2 tanks.
I have been toying with the idea of longer arms so full length T-Maxx cvd's could be used as well as regular Maxx wheels. But the problems of a diff cup solution is still there. A person could do my mod with the diff cups providing the T-Maxx cvd's will fit in the buggy diff cups.
