Sasha, 
Did it happen to be in Amatroi Alfa that you saw this car? If it is, then I
know the car. The Girling calipers are the "slide" type, so while they may
be twin piston, both pistons are on one side of the caliper, and the other
side gets "pulled" onto the disc. The GTV6 brakes have twin pistons, but one
on each side, so the braking force is more even, and the pads wear evenly.
Yes, thats right, the slide calipers under racing conditions will tend to
wear the "pulled" pad at a slight angle....
Stick with the GTV6 method, it's much less work, and works just as well if
not better than the Commodore method. If you can find the complete uprights
and everything, then it's an even easier swap job on the car! Pads are not
hard to find sasha, and there are some VERY good compound pads availabel for
road and for race.
