G2 X-Brace Conversion/ Need Help

[Pinball]

I am currently planing on purchasing a G2 x conversion. I have a stock E-Maxx and would like to know if everything bolts up directly?? While changing over to the G2-X I am putting in a HV Maxx brushless motor. I am also going to go with the 1 speed tranny and the gorilla motor mount. RPM suspension arms, MIP cvd' and some heavy duty shocks will be installed. What else would be a wise investment at this time?What kind of gearing should I use? Will the stock diffs be tough enough? Thanks,Pinball:
