The flywheel is about $550 at Sunset Porsche and in the $400 range for a lightweight aftermarket replacement with inserts. I believe most dealers charge around $800 for the part and $200 for the labor even though it's a 10 minute job once the clutch pack is out.

From what I've read in other forums I think you'll probably end up replacing the flywheel anyway so you might as well just do it all at once when it really does wear out. The only thing I would not wait for is a squeeky release bearing since that can cause more damage if it explodes.
