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?

I have an intermittent static issue. It seems to originate from my center speaker near the clock on my dashboard. When the suspension is lowered it it more prevalent but it also happens before I even start my car. There could be weeks between hearing it and other times it will go on for hours. I suspect I have a loose wire in the amplifier? Is this an issue anyone else has ran into?
Greetings all... Over in the Cayenne section there is a post about the PCM System error: UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN UNKNOWN when starting the system up... no ultimate resolution but the consensus for the cause is a break in the line... I have a 2004 Turbo Cab and installed a MoBridge system and have had ZERO issues. My Parents have a 2004 Turbo Cab where the previous owner went cheap with either the Nav-Tv adapter, the installation, or BOTH (But when you get an otherwise pristine Turbo Cab with 28,000 miles for $42K, you don't nickel and dime). The installer unplugged the CD changer and pulled the plug off of the fiber optic wires (that plugged into the changer) using a line break splice to plug the two wires together instead of plugging in a loop per the NAV-TV instructions. I bought both male and female loops so that I could put the vehicle cables into a new plug and install the other plug with the loop. Since the issue isn't resolved (but the audio works so this has to be the "break") I have to assume it isn't getting a good connection. Upon closer examination, the fiber optic cable ends on the loops are gold metal and shorter than the plastic ends in the car loop. This end difference prevents the plastic ends from seating far enough into the plug to make a good connection. Any advice on how to either replace the ends, or a part number for the original Porsche plug that I could match with a different loop? I am thinking that Porsche probably have a plug that goes into the CD Changer MOST connector for vehicles that don't have the changer installed...Thanks!!
Hey guys and gals I have a 2010 Porsche Cayenne base and I’m having trouble connecting my IPhone 6S Plus to my PCM running software version 1.47. Now I know that Apple phones don’t accept the sim access profile, but I can’t figure out how to switch the PCM over to Hands free profile. I went to my local Porsche dealer here in Tucson, AZ today and I told them that I had read online that they should be able to switch my PCM from SAP to HFP, but after 1 1/2 hours of trying they said that the couldn’t find how to switch it over. Any suggestions? Can it be changed using a durametric? Should I talk to another dealer in Phoenix? Any suggestion or insight will help. Thanks in advance.
Hey gang, hopefully someone can answer a few questions for me.
I have a 997.2 cab, and recently bought a set of Turbo II wheels – when I spoke to my local dealership, they informed me the offset was wrong and the wheels wouldn’t work on the car. Anyone have thoughts? What size tires are you running if you have the same setup? Any help is appreciated.
Here are the part numbers:
Front 997.362.157.02 – 8x11 ET57
Rear 997.362.163.02 – 11x19 ET51
