I can tell you they all make a little noise back there especially when you un load them coming off the highway stopping and starting. It seems these gear type diffs like heavier lube, it quiets them down a bit, they just dont have any spring tension to take up gear lash the way a conventional posi does, you got lash in the ring/pinion the splines in the axles and lots of little gears in the diff and it all moves a bit. The wavetrac is a ncely machined piece, I went with the 35 spline axles. In a 12 bolt application with the 35 spline axles moser uses a diff bearing where the bearing cage protrudes out the back surface of the race, so they had to make these ring spacers, you cant just stack the standard shims up against the cage. These spacers are only about 3/16 wide and just thick enough to clear the cage and then you stack the shims. It just seemed a bit weak, after talking with some engineers, I come to relize theres very little side loading there and once the bearing cap comes down and locks the assembly in place it aint going anywhere. Oh ya, I think the axles added another 100 lubs to the back of the car, there friggin huge. If your road coursing the car or even heavy autocross the wavetrac is good insurance. Wavetrac uses some serious steel in there units, I call it unobtainium, you wont blow that beast.

Great description Rich....
I took a hard look at the WaveTrac. Stout unit no doubt! I'm also keeping my options open for a floater rear (one day, phase two perhaps) and not sure I want to limit my options to one 35 spline vendor. I also agree about he noise, and possible breakage when beat on (my 31 spline axles are good to 700hp I was told), but decided to take the risk. We'll see how that goes...
