If the flywheel is not replaced, have it machined (resurfaced).

Unfortunately, it's a dual mass flywheel so it can't be machined, it has to be replaced. That's one of the things I do not like in the Boxster clutch.
With the pressure plate, I have the original pressure plate on the 928 after 110K miles and two clutch plates with nearly 50% more torque than the Boxster. Many other 928 owners have gotten 200K+ miles out of the pressure plate because of its' design.
In the end, it's always your money, but I'd keep the $250 for other things and replace the pressure plate when a crack is detected on one of the fingers at clutch plate change-out time. Here's what to look for to determine if you should replace it:
