Is this "slop" at the diff outdrives or is this measured at the wheels?
Every gear type transmision has some sort of slop.
If not the gears would be very tight.
I build Spec-R diffs and the 3Racing gear diffs and they both have a small amount of slop.
It gets bigger when you have the dogbones on it and turn the wheels but when moving the outdrives it seems very little.

Ps any one else having problems with leaking Spec-R diffs?
