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?
“Thank you worked like a charm!!!! I have a foxwell, getting error codes 31 ignition circuit - side airbag , driver
and 21 ignition circuit, driver
no idea what to do. Horn works depending on its mood. “
Any suggestions would help. I’ve taken off the door panels and disconnected and reconnected the airbags.
I had to disconnect the passenger side door airbag as part of door panel removal, to replace the door lock mechanism. To check that I replaced the part correctly, I reconnected the battery and turned the ignition key, and got an "Airbag Failure" warning. The fault didn't clear even after disconnecting the battery, reconnecting the airbag and closing up the door panel, and reconnecting the battery. I confirmed the airbag was reconnected. I suspect that it may be a "latched' fault that can only be cleared via the Durametric tool - thoughts?
