What would be the advantage of this, as opposed to the stock rubber item?

Good question, let me address it.  

First off, unless the part has been replaced, every quattro out there is in need of a new center bearing support.  The stock unit, being made of vulcanized rubber tend to sag and eventually rip leaving no support for the driveshaft between the differentials.  Rubber may be good at isolating vibrations, but it is not good at preventing deflection movement due to counteracting forces.

While at Eurospec, I noticed that the TransAm and V8/DTM cars had center support bearings made of solid, machined aluminum, and this gave me an idea. 

I have seen a quattro on a dyno running thru the gears, and in a stock vehicle the driveshaft basically loops around the inside of the bearing carrier, creating a lot of vibration and movement.  Also, theoretically, such a loose bearing will allow the driveshaft to wind up more than a bearing with very little slop.
   Overall, the car felt smoother under hard acceleration and throttle transitions, longevity is a plus, and knowing that your drivetrain is
maintaining proper alignnent is also key.  HTH, I think you would really like it on your car.
