upgrade info

I have a revo with the 2.5r motor and I looking to do some upgrades like installing the Forward only conversion one question I have is when you do the FOC do you still need to buy the center diff as well. I guess what it is reading all the descriptions are getting me confused.

other upgrades are adding the wing and a sway bar kit

the foc kit does NOT need the center diff ..its a matter of choice to get it or not

is there really any real big benifit to have the center diff I do plan on being in some events this year race wise
