boxster ims bearing
i have a 1999 boxster 986 with 72,000 miles on the clock.
recently i am reding lots of articles about how prone the early boxsters are to getting an intermediate shaft bearing failure. even on a book i bought recently it says you should change the ims bearing at least every time you change your and flywheel, since it will be easy to reach then, and failing to do so may cause major damage to the crank instantly.
the thing is, my boxster still has its original clutch on it, and the car runs like clockwork. should i just remove the clutch and flywheel,(which i will then change to new ones once theyre out) to change the ims bearing, or should i wait for the clutch to fail first?
is the ims bearing failure really that serious, that it doesnt give you any notice prior to it failing?
any suggestions please?

If you want to replace the IMS bearing with an aftermarket one (I do not think Porsche offers the IMS bearing separately for it does not recognize the bearing as a servicable item) that is up to you.
What you do with the clutch/FW at that time is also up to you. 2.5l Boxsters have a rep for going through clutches though there are plenty of exceptions. In your car's case, it may be one of the exceptions. So a clutch job at this time could be very premature.
BTW, my 02 Boxster's clutch is original and coming up on 250K miles. IMS bearing is original too.
Sincerely,
Macster.

thanks macster, you put my mind at rest 
after all, im sure that many people who own boxsters and are not much into cars dont even know about the ims bearing failure issue, and im sure most of their cars work fine!
so i think ill just take my chances.
i asked the mechanic about my clutch and he said it still has a very good "bite", so as you said, its not worth changing now, although i doubt it will last as long as yours
Cayman Cab S, thanks for the info. i will definately look into it, after all its worth putting your mind at rest, and not go through the extra expense of changing the clutch prematurely.

Like everything on the net, the IMS failure is over-hyped. I've owned two Box's and never had an issue with either. Combined mileage of over 130,000 miles with no problems. Make sure you have the proper maintenance, use high-grade fluids and drive it like you own it. Then, even if you do have a problem (which a few do) you will have enjoyed the ride. Fix it, and drive it harder.

I agree that you should drive it hard/'like you own it' and not worry too much about the IMS bearing. I bought my 2002 4 summers ago and have put on 45k miles with no engine problems. With that said, I did purchase the IMS Gaurdian system(not yet installed) because my original clutch still feels great at 90k (no bearing update for my car soon) and if the IMS does fail, it can be expensive. I hope I never see the Gaurdian pay off, but the peace of mind is worth it to me. I have spent $400 on a lot of other things on the Boxster already anyway!
