The $200 was a follow-up to OP's comment, not an estimate of 996 clutch prices: "By the way, the rich got that way by not spending money recklessly or needlessly. Even if it is only a couple hundred bucks.

Also, I don't think a new clutch is $200.
its not always about thickness of the surface. Over time and heat cycles the friction surface can loose it integrity. If you are gonna spend the coin to drop the motor and transmission then it only makes sense to replace original 10+ year clutch due to the labor cost of separating the two units. A clutch disk is 300-500 bones-ish. The labor is 3-4 times that much. It is a no brainer to replace the original clutch if you drop the motor and trans out, but to each their own its not my money.

If you are gonna be dumb, you better be tough.
If you play stupid games, then you will win stupid prizes.

new clutch $700-$800
DM flywheel $1100-$1200

add $2000 to make it right for next 70K miles + resale ease/value

thats how smart people do the math

this is a no-brainer

Wait, all those first gear street turns haven't destroyed the clutch?

Before the birth of my 2nd kid, doctor recommended that while ALREADY IN THERE, do we want her tubes tied for a little extra charge? BTW, her tubes were perfectly fine and of course, can wait till later for the doctor to go back in and get them tied. The choice for my wife was pretty easy

Oh boy, here we go again.

If your clutch is still like new but you cave in and have it replaced, might as well get the inside of your bell housing detailed as well ala KK style. You know? While you're in there...

Default Alpine - thanks a lot!

I remember going to Pebble Beach four years ago. While watching folks prepare to drive their priceless cars onto the lawn for the concours event, I saw a white haired gentleman with Q-tips cleaning out the treads.

I thought: "life is simply too short to actually spend time doing this!"

Funny thing...if we could see the future, we'd all be rich - but I have yet to see a wealthy fortune teller.
Schnell, re-read my post about the rich. ...not spending money needlessly or recklessly.... Of course that includes not being "penny wise pound foolish".

I've always put my hard earned money into assets that appreciate not depreciate. (I'm a fan of the Dave Ramsey radio show).

Every time a human with a wrench in his hand intervenes, there's the chance of causing more problems. I want to keep others away from my work as long as possible.

I am the same way when working on my own fleet. I don't want to do the job again, because I don't have the time to. I finish a car, and I don't touch it for years, other than to keep it serviced.

I definitely concur - while I enjoy shining up the Porsche, I derive even more pleasure from smashing bugs all over the front of the Porsche.

Default IMS replacement update

They called and said I have 60% left on the clutch (at 39k miles). They also said the flywheel has some small grooves worn into it. They said: "it's up to you whether you want "new" stuff".

My question is what is the effect, if any, of having any imperfect surface on the flywheel? I can't feel anything when I drive.

Thanks for your input.

Since it is within specification, I say Let It Ride. There's no point in replacing something that is still 60% good just because you are in there.

The only thing that can wear grooves into the friction surface of the flywheel is the clutch, and the only grooves I've worn into a flywheel were due to wearing the clutch down to the rivets. So that part seems a little odd to me.

If the shop does not think there is a safety issue, button it up and drive it for another 30K miles.

As a data point: My C4 clutch was worn completely down (I had just started polishing one rivet) at 60K...

Your car is doing 3K miles a year (based on the mileage / 13 years) - so at this rate you could go about 15 more years before the clutch would be completely gone...

Save the "$200."
