Time for a clutch, Questions!!
So I have now been a porsche owner for 3 months and my 28k miles 996 now needs a clutch! Funny thing is i bought this car so I could have a nice sports car and not turn wrenches on it like I do my high HP 3rd gen rx7. So the plan is not working out!!!
I am considering doing the clutch job myself since I have done many before and can not think to pay $2000+ for it. My question is what all should I replace while doing this? (Disk, pressure plate, throw out bearing, RMS, ??) How big of a job is it? Were can i get a shop book or disk to help out? What brand clutch? Thanks in advance!!

Can't help with the clutch repair, but why, per se, did it fail in just 28k miles? Do you track this car? Do you heel/toe shift? Maybe the prior owner wasn't to great a driver? seems WAY too soon.

make sure you get a porsche OEM clutch kit... stay away from the SACHS aftermarket porsche clutch kits.... unless they are the performance clutch kits that is... Porsche OEM is very very good.

Driving a manual transmission car in an urban environment just takes skill and finesse. While a clutch may only last 80K-100K miles in an urban setting, anything less is a reflection on the operators abilities, not the capabilities of the hardware.

I think it has more to do with usage. If you drive 50 miles to work and depress the clutch 10 times, and I drive 5 miles to a restaurant, and depress the clutch 20 times, I'm going to go through my clutch before you...all things being equal.
I've been in a lot of cities, but there's nothing like New York City when it comes to tons of grids and lights. Not even Bos, Chi, or SF come close. Come hang out with me in midtown one day after work; I'll show you what I mean. You might depress the clutch 5 times just to move a block (1/20th of a mile).

I have to agree with Orient Express here - my '76 911S clutch went 138,000 and that included a fairly large number of trips to Texas World Speedway. My '74 914 clutch was still going strong at 110,000 miles when I sold the car and it was primarily an autocross car.
I expect my 996 clutch to at least 100,000 miles.

It's so easy to blame it on the car's engineering for issues and never the nut behind the wheel.

You guys are missing the point. In autocross, you are in gear, clutch in, clutch out, in gear. And how many times are you hitting it hard like that a month? Every weekend as most? That's 4 times a month. Try hitting your clutch hard every single day on city streets. Not commuting outside the city. But in it and into it. At very low speeds. Here's what traffic is like: clutch in, roll on throttle, clutch in, roll on throttle, clutch in, roll on throttle, over and over and over again. Going fast enough to stay in first gear without clutch is a blessing. Even stopping is a blessing.
Anyway, I'm not stating that's it's not possible to go far on the clutch; rather, I was stating that it really depends on how you're using the clutch. Racing, autocrossing and highway driving is mostly an off clutch experience. Traffic in metro areas is more of a very slow, painful, constantly clutch-slipping experience.
In fairness, I don't see too many Porsches commuting in vicious traffic. People must be driving their second cars and saving the Pcars for faster flowing drives. Here in New York, that's anytime between 730p and 630am.

This does bring up a relatively important (but supposedly well understood) question:
Are the following maneuvers good or bad for the clutch?
1. Take your foot off instantly ( aka burn rubber) ..... Good / Bad ?
2. Take your foot off gently and give sufficient gas so as to not stall ..... Good / Bad ?
3. Rev match to previous gear while upshifting/downshifting ..... Good / Bad ?
4. "Holding" the car uphill (preventing it from rolling back), by releasing the clutch halfway ..... Good / Bad ?
