This is what Yokomos designer said about the lowering of the Diffs
The front and rear drive pulley was reduced 6 mm and the drive axel was lowered 3mm. This reduces the gyro effect caused by rotating parts when racing (the effect will be less changes direction of the rotation axis), especially due to better movement of the roll direction, sharp crosscutting and cornering become possible. The throttle response is also improved by the weight of the pulley. Acceleration and electric efficiency has also improved during escape at the corner.
So it is gyroscopic effects they are trying to reduce. To reduce the gryo they reduce the diameter of the diff pulleys this also allowed the diffs to be lowered 3mm which helps lower the CG. Yes that changes the angle of the axles but I don't believe it has anything to do with binding. They are doing everything possible to lower the CG, reduce the rotating mass, and minimize gyroscopic effects. That all makes sense to me.
