I've got 65K on mine works well.
Although my engine seems to be making a louder rattle when its shut down after parking. I'm thinking of doing this retrofit and pushing the shocks out later.
Kind of pricey to do both right now.

The clutch will get super heavy or light. Normal slipping etc.

Dude tell me about it,the overpriced crap from Porsche is starting to annoy me now that I'm looking at other cars. I was looking to switch to a 01' z06 recently and called shops for quotes.....new 09' z06 shocks(fit on c5 vettes)....$400($236 parts)....installed.

Every M96 powered car I see with more than 40K miles is in need of a clutch.. Thats why I include the cost of a new clutch package in every IMS retrofit package that we complete.

Jake, how do you define "in need of a clutch"? If I experience no unusual noises, no burning odors, no noticeable slippage as I engage the clutch, can I still be "in need" of a replacement?

(With 48K miles, if/when I do the IMS retrofit, I'm sure I would go ahead with the clutch anyway. But I was just curious.)

How often do you see an M96 that doesn't have a bad IMS bearing?

We've seen plenty of cars make it to 70-80K on their original clutch. It seems to be somewhat hit or miss, and it also depends on how the car is driven. Now, if we're pulling the gearbox for an IMS update, it makes sense to do the clutch while things are apart.

82K on my 2001, no signs of needing a water pump, AOS, RMS or clutch yet.....

By the time the clutch shows symptoms of needing replacement you'll also need a new flywheel..

At 40-50 K the clutch disc is worn very close to the rivets, but that is dependant upon the driver.

I believe in being proactive, if the tranny is pulled you replace every part that may see wear in the next life of the replaced clutch.. It only makes sense.

When I assemble a new engine it gets a new clutch, pressure plate and even a flywheel if its worn, so I can rebalance the entire assembly and keep it that way for as many miles as possible without parts needing replacement.

These days the only clutches we see are when doing IMS retrofits or when attempting to save engines that have already featured a failure..

Most flywheels will flunk at least one of the tests that Porsche calls for by the time the clutch is worn.
