Ok my first question is: what does a shim for the dif exactly do
Second Question: is the light kit for the merv worth getting and what is the traxxas connecter for on the wires from the switch?
The shims help reduce the slop within the diff which then reduces the chances of it stripping...in a very dumbed down explanation I guess haha
And no input on the lights sorry
You ain't bashin unless your crashin!!
