I noticed that only the outer edge of your friction material looks like it had made contact with the flywheel / pressure plate.

This raises questions:
1. Do you think you got the surfaces seated/broken in adequately?

2. Did you replace clutch disc while re-using the old, worn pressure plate or flywheel, or did you replace those components as well? (If you reused them, what condition were they in?)

3. Do the pressure plate and flywheel friction surfaces completely cover the friction material, or is there some friction material that overhangs the mating surfaces?

Comparing to a "stock 986" clutch disc (for new Sachs 5-speed unit, see attached for comparison) the 987 one you show has some differences. Maybe mismatching the 987 clutch disc with the 986 flywheel and pressure plate caused this problem.

In case it helps, the outside diameter of this pictured 986 5-speed clutch disc is 9-7/16".
