FVD sells 996 GT3 Cup brakes at their website.

Drilled disc left GT3 Cup with centerlook 996 351 409 90
Drilled disc right GT3 Cup with centerlook 996 351 410 90
Mod. 996 GT3-CUP, Brakes, Motorsport.

One local 928 racer is thinking about using them in his '78 race car. He asked me to check around if anyone had these on hand or knew their measurements. FVD would measure them for him but they do not have them at the moment and will only get them when someone orders a set.

Below is picture what I believe shows '99-02 GT3 standard size disk measurements. If anyone has those Cup disks could you please check if they are same as in pic. Thanks.

I know that the measurements of the Motorsport Discs for the last model of the 996 Cup Car are identical to those of the steel discs for the last model (Mk II) of the 996 GT3. The diameters are

Front 350 mm
Rear 330 mm

As for the measurements of thickness and offset, and the bolt pattern, I can't help.

What are the measurments of on the left part of the diagram you posted?
