High mileage 996 TT?

My first clutch had to be replaced at 372,000 miles, only because a tab on one of the bearings broke and caused the pressure plate to crack, the bearings had been replaced before that at least once. Had I done them again prior to failing I'd be on the same original clutch.
Once the pressure plate cracked it made sense to do a new clutch, pressure plate, flywheel, both bearings and rear main seal at the same time. The clutch had plenty of friction surface left at that point.
My car sees highway, track and a ton of bumper to bumper traffic every day. It hasn't just lasted due to just highway miles.
It's one data point anyway, not necessarily a trend.

T2, how many clutches have you gone through in that amount of time? lol How much mileage are you guys getting out of a clutch? I'm looking at a car that had it's clutch replaced just under 20k miles ago. Is it good for another 10, 20, 40k miles? I know it really depends on how it's driven. But on average how many miles are people getting out of a stock clutch?
When I bought my car, it needed a new clutch.
Once the car was opened-up, all indications were that the clutch was original; 140k miles.
Interestingly, there was still a fair amount of friction material, and the engage/disengage point was still reasonable. The problem was that the raised areas around the clutch-plate springs were starting to make a little contact with mating assembly, and preventing full engagement pressure...

The tech is pretty good about replacing the clutch control shaft needle bearings and related hardware ( dust caps? ) whenever the transmission is out. He has so far not advised me to replace the release bearing.
Like T2 has managed, I expect to get 300K+ miles out of my Turbo's clutch.
(My 2002 Boxster has over 305K miles and is on its original clutch so getting 300K+ miles from a Porsche clutch is certainly doable.)

WOW! I'm blown away that people are getting that kind of mileage out of their clutches. I know some of those numbers may be anomaly's but that's really saying a lot. I realize with a modded engine, the stock clutch can't hold too well once in the 550-600hp range and a beefier clutch is advised. However, the car that I'm looking at had a new clutch 20k miles ago and is stock except for an exhaust, so the new clutch should be good for quite some time. Thanks, that's real piece of mind if I proceed further and move on to the next step which would be to get a PPI.

My 2003 Turbo has over 148K miles on its original clutch. Had the transmission out at around 120K miles to replace a leaking RMS and the clutch disc had no measurable wear.

As an added data point, my RMS was also found to be weeping when I had the clutch done; again, at 140k miles.
Dual mass flywheel was completely fine.

Great info in this thread. I'm also blown away that folks can get such great mileage out of the stock clutch.

Additional data point for modified car:
117K mile turbo with 24/18gs -turbos installed at 68K
Original clutch
Heavy stop and go traffic Houston - (17 mile commute @ 45 minute average)
No hard launches
Multiple 3rd gear pulls
Clutch holds strong w/o chatter

T2, is your car 100% stock? Any Mods whatsoever?
Just curious as I have a 2002 that Is 100% stock & intend to keep for a very long time. It is my DD with lower miles and I'm just curious if i can see this kind of miles with mods...i.e...basic tune...exhaust...nothing crazy

My car has very large protomotive intercoolers, kw clubsport suspension with gt3 adjustable sway bars and tarret drop links, moll blow off valves, otherwise stock.
I attribute my longevity partly to my location from work, I live in an area where I have 12-15 minutes of 60mph warm up and cool down, otherwise it's a ticket for speeding.
These vehicles are made to be driven all the time, in all conditions, reliably. Some of the best driving is in 6-8 inches of light fluffy snow with proper winter tires. Many never get to see how well this car can do in the snow, it's phenomenal and very stable in those conditions. The looks you get are some of my fondest memories of driving.
Buy it, drive it, enjoy it...in that order....your results may vary....I'm T2...I'm not running for office...I do however, approve this content.....
