Anyone out there done this? 

Reading their instructions they recommend 1.75"-2" spacing between the wheels at their closest point.

Using no spacers or washers at all other than the toe out wedge (at the half toe out setting) the closest the wheels are is over 2.25" apart.

Is this anything to worry about?        Other than majorly reworking the brandnew tailpieces I don't see any way to get them closer.
