Thought it would be a good idea to start a thread and hopefully collect a list of all the part numbers that make up the Performance Pack available in the EU and some other markets.
So far I've been able to find:
Roof spoiler lip
Part # 5G6 827 940 041
Brakes, which I believe are the same as the GTI Clubsport brakes. The rear pads I think are the same as stock.
Pads Front: 5Q0 698 151 G
Brake Rotors Front: 5Q0 615 301 C
Pads Rear: 5G0 698 451
