My take on NVH is that given the stock drivetrain shifts (no pun intended) around wrt the chassis, the play in the bushings isolates the internals of the tranny so the shift fork, sleeves don't "rattle" as these movements occur. To borrow an expression, rebuilds are more expensive than bushings. Granted, not a concern for racers but that isn't the application here.

I have to agree and have thought this for a while. The bushings allow a certain amount of vibration to escape, reducing an element of potential damage. Other opinions are of course available but I sold mine a while ago.
