Suggestion
I instructed him to replace the Sachs clutch with a factory part and to get a refund on the Sachs clutch as it clearly never operated properly.
Replace with a non oem clutch will add additional stress

Suggestion · Original poster
Part of me worries that replacing with a non OEM clutch will add additional stress to the drive train and open a can of worms.

Avoid using the car in such a way the clutch slips again.
Use clutch kit without new flywheel as i expect it

Only planning to use clutch kit without new flywheel as I expect it to be fine.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So yesterday I had my first clutch slip. I have 31k on the original clutch. It doesn't slip in any gears but when I shifted into 3rd during full throttle it showed signs of wear. Couldn't smell clutch, until I opened the hood and that smell is unmistakable!
In preparation for the inevitable I went on Pelican parts and saw the OEM clutch kit and about a 100 other options. I want to get opinions on which clutch to select. I have never replaced clutches in previous cars with OEM and had great success with ACT. Part of me worries that replacing with a non OEM clutch will add additional stress to the drive train and open a can of worms.
Since this is my first Porsche any opinions would be greatly appreciated. This is a not a daily driver and I will be doing some track days over summer months. Only planning to use clutch kit without new flywheel as I expect it to be fine.
...and yes this job will include RMS, IMS, beer.
MY99 C2 with dual row bearing....
If you are going to leave the engine stock go with the stock clutch. It fits. It works very well. The short life of the one in your car is an anomaly probably arising from the previous owner's treatment of the clutch.
Avoid using the car in such a way the clutch slips again. If it slips any more it may overheat the flywheel and it may become grabby with the new clutch hardware installed.
Yeah, I just got the car 2500 miles ago. I get it's early, but I don't have a choice. I'll stick the the OE or the Sachs options then.
Macster, good note on the clutch slipping. Once I start getting the dreaded slip in higher gears I'll change it out.
Thanks everyone!
If the clutch is slipping in a lower gear, 3rd in this case, it is time to replace it. (Actually, if the clutch is slipping in any gear, it is time to replace it.)
Generally a clutch doesn't slip in lower gears because of the torque multiplication of the transmission reduces the force the clutch must transmit. It slips in higher gears, the best "gear" is the one that is closest to having a 1:1 ratio, because there is no torque multiplication.
Up to you, but I wouldn't wait.
Be sure the brake and clutch fluid is flushed/bled after the clutch job.
I have been driving Porsches as my daily driver since 1991 when I purchased a �88 944S. I have had several daily driver Porsches since that time, after the 944, they were all 911s. I am very familiar with the product, how to drive and maintain it, and I have a long history of service on all of my vehicles from Porsche direct only.
I had one issue with my 2001 996 Cabriolet when I undertook replacement of the clutch; a minor rear main seal leak only. I purchased my car from Porsche as a lease return from a Porsche employee with 50,000 km on it. My car had more than 160,000 km on the original clutch, and it was operating flawlessly when I undertook this upgrade. I elected to upgrade my clutch and flywheel as I wanted the minor leak rectified, and I attempting to be proactive to save myself future labour to disassemble the same portion of the drivetrain to replace the clutch in the future and to increase my car�s performance. My dealer is a Premier Porsche dealer, the Sachs clutch and lightweight flywheel were supplied by AWE Tuning.
The work was completed in the spring of this year, and the car returned to me. Very soon after its return, it became clear that the clutch was not operating properly, and within approximately 2000 km the clutch began to slip and fail. The car was returned to Porsche, who disassembled the clutch to diagnose an repair.
At that time, AWE refused to replace the part without inspection. I waited with my vehicle disassembled for more than 2 months for the parts to be sent away, inspected, tested etc. The Porsche dealer's ability to install the part correctly was brought into question by AWE (I find it extremely unlikely that a dealership of this calibre and reputation could install a clutch incorrectly), my driving style and ability was questioned (clearly, with 160,000 km+ on the original clutch and very little wear it was not my driving style), so by the process of elimination, I do not see how the issue can by anything other than a defective part and/or supply of the incorrect parts. After all of this, it was discovered that AWE had indeed supplied incorrect parts for my vehicle. In the end, the part was replaced and reinstalled.
The problem did appear to be solved, and the clutch did operate properly for several months; then the same symptoms reappeared, and the clutch began to slip again with less than 4000 additional km. That is a total of approximately 6000 km to burn-out two brand new clutches. I don�t that believe that the worst driver could be responsible for that level of wear, so once again it�s not the driver. If it is extremely unlikely that a Premier Porsche dealer installed a clutch incorrectly once, then it is practically impossible that they did so twice, so it�s not the installer.
I returned the car once again. Inspection of the parts shows unusual wear and heat damage. The flywheel is scored and worn as well. I am not a mechanic, but clearly there was something wrong with these parts individually, in combination or with some part that is incorporated in their installation.
I told my service advisor that I did not want to go through the same nightmare again (the dealer was amazing and extremely helpful throughout the entire matter). I instructed him to replace the Sachs clutch with a factory part and to get a refund on the Sachs clutch as it clearly never operated properly. Once again, I was buying a new factory replacement clutch when I didn�t need one in the first place! In addition, the lightweight flywheel is damaged and of no use to me. Luckily, I kept the original flywheel to reinstall, but I had still paid for a flywheel that is either defective of incorrect and was now clearly damaged.
AWE Tuning refused to do anything further to mitigate my damages, simply saying that their parts dont fail.
I was without my vehicle on two separate occasions for extended periods of time, I was forced to purchase a new factory clutch when I didn�t require one, I purchased a flywheel that was unusable and I am out tens of thousands of dollars as a direct cause of my purchase of AWE Tuning supplied Sachs parts.
Its only one person's experience, but after more than 20 years of owning, servicing and modifying Porsches, buying Sachs parts from AWE Tuning was the worst experience I have had.
I had a similar experience with AWE couple of years ago. They sent me a wrong part for my Audi and wouldn't believe me when I told them it was wrong. I had to take my car to dealer and have them validate that it was wrong, on my dime. Fortunately, I was able to get refund for the part, but overall very bad experience. I've never bought anything from them since then.
