How many miles did you get out of your clutch?

I am having my clutch replaced because the pressure plate was going bad. I'm also having the IMS&RMS done while they're in there. I was able to get 46k of life out of it and was wondering when others had theirs done.

Clutch life varies widely between driving styles and environment's, some only last 40-50K miles, other go over 200K. There is no fixed distance.

91k miles on original still with a perfect release point, no slipping. Only reason I think about changing would be to try and save having to replace the flywheel

96k miles. Both clutch and flywheel were shot. Driving style is the greatest determining factor in clutch wear.

Changed mine at 90K, though it wasn't slipping in the least. Did so because, (1) I wanted to do the IMS bearing, and (2) Jake Raby has been advocating that you don't want to wait too long or the rivets will be chewing into your flywheel, necessitating that it be replaced as well. I got it about right...mine was worn to the point where that was about to start happening. I think I'm not too hard on a clutch, but someone else owned the car for the first 20K miles---I have NO idea how he drove.

The IMSB? Looked/felt perfect. It's a peace of mind thing I guess

Not sure.

I've had my car for 8.5 years and I purchased it with 76K miles. Don't know if one of the PO's ever replaced it. I'm at 132K now and clutch still feels great.

Does changing fluid extend the life of the transmission?

I'm on 97k, bought the car at 89k. Clutch wasn't included in any of the documented previous Maintanace so to my knowledge clutch is still original.

These are shots of the clutch that came out of my 996 when I had to pull the engine for an intermix issue. This clutch went in @ 76,133 and the engine was pulled @ 126,600ish, so the clutch has almost 50,500 miles on it.

The clutch in my Boxster went 142,xxx before it was dead. Clutch life is defintely related to where you live and how you drive the car.

Hmmmm, J.Fro, that clutch does look nearly new, the wear is not even near the rivet heads yet.

Mine was worn down to the bottom of the grooves before it finally needed replacement. I had put on 20k miles myself at 75K miles and I think the car had its clutch replaced at 35K miles already so 35k-40K is my cars average.

I measured the remaining disk material to be 3/16" on the DMFW side and 1/8" on the transmission side of the clutch before it started slipping during hard acceleration.

I was a little surprised to see that on the new clutch the disk material is only ~ 1/4" thick per side at the start so its lasts a long time.

I think I read that 30k miles under typical hard use is normal but depending on driver techniques and use it could last 2-3 times longer so 30k - 90k miles.

Many drivers let the clutch slip a lot before fully engaging so that wears the clutch faster. I typcally "drop" the clutch and rev match well so there is little slipping and hence less wear.

If you ever smell burned clutch then you need to improve your technique to get longer clutch life.

Even when doing max acceleration standing starts during Auto-X I don't burn the clutch. It just takes practice and good timing to perfect the technique to extend the life of your clutch.

The Boxster is the first of about 6 cars that I have ever had to replace the clutch on within 90,000 miles of driving them.

Check out mine when I replaced it, just 1/16" clear of the rivets and worn to the bottom of the groves, hence there are no groves anymore.
