I've got a 2008 997 C4 w/ 56k miles on it. It was cold this morning (30 degrees F) and I noticed clutch slip for the first time since I bought the car in higher gears under full throttle. The clutch pedal feels very mushy and lost alot of its spring on the return. I stopped by my local shop and he confirmed its the clutch.
The car is my daily driver but I do autocross about once a month and intend to track in the future. I told myself I'd get the light weight flywheel when its time to replace the clutch, and so it seems that time has come. I'm not adverse to the extra noise of the LWFW, but I've heard that you shouldn't do this mod on a C4. I see sharkwerks has a C4 project car with the LWFW so I assume it worked out, but who knows.
Aside from the flywheel obviously I need a clutch. I've been looking at the Sachs stage 2.5 performance clutch kit, and it seems like a good option. I've also heard that the BBI clutch slave cylinder is an upgrade that would be helpful for clutch performance and feel.
-Anyone have any experience with a LWFW on a C4?
-Anyone have any experience with the Sach's stage 2.5 kit on a C4?
-Any other clutch kit recommendations?
-Anyone have any experience with replacing the clutch slave cylinder?
Note: I'm going to get my IMS bearing inspected but if its not leaking I think I'm going to pass, seeing how I have 56k miles on it with no issues. Perhaps its past the infant mortality stage?

Help - i have a 2003 Boxter tiptronic s - in great shape other than a shrill loud noise like a Kazoo that only happens above 78mph - it sounds as iff coming from around the mirror area of the windscreen but then occasional sounds like its coming from the speaker area passenger side - that being said could be sound transference. Read a number of blogs about badly fitting windscreen so put tape over top rubber seal and body but still there - - as a say like a kazoo at 78mph with hard or soft top - absolutely driving me mad - any help gratefully received.
I just bought myself my first Porsche, a 1998 Boxster. I have an issue with the soft top that I'd like to get some guidance on.
The top goes down smoothly with no issues. It also comes up smoothly until it is nearly all the way up. Just before the dashboard Top light goes out, there is a pretty sharp metallic twang or snap. It did this when I was looking at the car before purchase, and it did it again this evening when I put the top up after driving the car home. I'm assuming it's getting caught on something but I wonder if anyone might have suggestions on what to look at given the late point in the cycle where it occurs?
I am completely flummoxed by this noise I am getting in my 2004 Turbo Cab. A couple nights ago while driving home with the top down, I noticed a rattle different from the normal sound of the motor and not accelerating/decelerating with changes in engine RPM. It occurred at 1800-2000 rpm and was most noticeable when decelerating in 2nd gear in my neighborhood at slow speeds (~20MPH)... with a helper on the throttle and the engine compartment open, it sounds like it is coming from the right side-top of the engine, around the Hydraulic reservoir. Putting a spanner/wrench on the component and up to the temple seems to have confirmed this as the source. I checked my manual and the Pentosin level (mid range on the HOT side of the dipstick at operating temp) I realize that Porsche recommends checking at 20C but I live in Texas now and that won't happen until November. Just out of curiosity I looked at the clutch reservoir up front and after removing the gooey trim cover, found it leaking (Seeping) from the recently replaced cap and appearing to be overfilled. The car has never really been operated in the 8 years I have had it in particularly high average temperatures, so I am hoping that the front is thermal expansion. Any thoughts on this matter are greatly appreciated... Loren? What Say You??
Thanks in advance,
Hello there, this is my first post here and I’m writing because of problem with my boxster.
Today in the morning I’ve started my 2002 boxster and noticed strange sounds from the engine/ rear side of the car
It’s a metallic, grinding sound like a loose piece of metal or something like that
Sound disappears when you press gas and comes back once you loose the pedal, I don’t know if it changes while engine is warm
Also, check engine light shown up yesterday, when I connected my BT OBD2 there was no error code.
I came with that to workshop also, and they said it’s a catalyst efficiency error.
I’ve had that error code a while ago, I’ve replaced mass air flow meter and check engine light disappeared.
I think it might be a problem with maf again because I bought not the cheaper, not the original one, but why are there these strange sounds? I’m worried about this. Could it be catalyst this time? Or again should I replace maf? This time I’ll buy original one.
here are two Videos I made
Also I’m sorry if you can’t understand something, my english is not perfect.
Thank you for all replies, I hope we will solve that problem together
