Alum Hexes, Arms (just to have), Hinge Pin plates (Just to have), 15-18 pinions (dependent on the track), 1258TG is brutal, your body should fit with no issues, Def get a few stiffer rear springs (just in case), The towers if your concerned about weight... However, with all that said.. I haven't had anything break as of yet.. It's pretty much solid, if something does break you'd have time to order it vs. needing it right then and now to finish a race lol.. But it's good to see a Traxxas convert stepping up to the big league lol.. I was right there with you dumping tons of money in my Slash 4x4 with no chance at ever competing.. lol !
