Wow. That think must RIP! I've seen those chassis braces all over the Internet and heard widely varying opinions. I really don't plan on launching this thing off a cliff. The chassis brace seems like it'd just add unnecessary weight, no? Have the 6s and new motor stressed the diffs and shafts at all? What diff oils do you recommend? I'm almost to the point of wanting to change my diff fluid. I've only run about a dozen packs thru my baby but I want to take hook care of her.
