Now onto batteries will a 30c rating pack be enough for stock 17.5? Plan to go with GensAce I have had great luck with them in my 1/8ths as well. I am not even close to the fast guy at my track .... still working on driving skills so keep that in mind.
I run Ofna 3,000 diff oil in my B4.1 Gear diff. It feels just as smooth as a ball diff
The battery will be fine.
