Bob O,
I think you should do it. If I'm not mistaken the experts on the subject have written that if its going to go, it will do so by 70K. Sounds like you are in the eleventh hour. But on the other hand If you're still on your original clutch you might have a couple more years left of clutch use. The way I looked at it....a clutch job at an Indy shop will cost you $1200. That's works out to a couple hundred bucks a year if you can get 10 years out of it. I'd rather skip the $400 lost in doing the clutch 2 years prematurely and reduce my risk of DEFCON 3 down to probably less than what..1%? Meanwhile you still have a new clutch at the end of it all, albeit adding another $600-$800 to the job.
There's a guy on YouTube who did his 996 Carrera in his garage without any experience taking apart transmissions. So an experienced shop could do it no problem, 8 hours tops? I guess that's one of the great things about these newer Porsches. It's much less complicated than old 'hand assembled' Porsches.
