Help with brake theory/design

Yes.  Not a Scirocco but what I did was use a poorer quality pad on the fronts.  That's all.  I can't remember what I used.  It was years ago on my GTX.

  Here is a question for those who have really investigated the braking on a
  Scirocco:

     I would like to change the braking bias a little.  For the track car I
     want the rears to grab a little earlier and stronger than they usually
     do (so I don't get 90-95% front braking).

     I know the front brakes are large because they do most of the stopping,
     but I want the car to kind of "squat" in the back end a little more
     rather than upset the balance and nose dive when I hit the brakes hard.

     I will be using the 10.1 fronts and rear disc

     So what is the best way to accomplish this?

     I have thought about swapping the disc prop. valves for a set of drum
     prop. valves, with the hopes that the drums will allow more fluid and
     thus pressure to flow to the rear discs.  I am not sure how much of a
     difference this makes (or even if the drums will increase the rear disc
     grab or decrease it)

     I have also thought of simply removing the prop.  valves all together,
     but though that would really upset the balance of the braking system and
     cause the fronts to be much to weak.

     I have even toyed with trying to rig up a wilwood dual master cyl so I
     have one for the front and one for the rear :)  But figured that was way
     too much work and over kill for a light car.

     Anyone tried to adjust the braking stance of a Scirocco?
