It was recently brought to my attention that the heads of the wheel lugs in my car are 17 mm instead of 19 mm (factory lugs). Is there any problem with that? Is it possible that also the length of the lugs is not standard?
I am going to get rid of the lock keys. Therefore I will need to buy 4 new lugs, if I keep the other 17 mm lugs. Any chances that lugs with same diameter and length, but made by different manufacturers, may have different weights , which would affect the wheel balance?
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?

Hi - 2002 996: Scoured the lists but can't find this particular cluster problem anywhere. In short, my salvage cluster shows a list of errors on start up but my original was fine.... Here's the details. My current cluster shows an intermittent airbag failure warning on the led screen followed by the idiot light. It usually occurs at start up, clears at the stalk and the idiot light remains on, but flickers on occasion. My mechanic had ruled out everything he could related to the airbag warnings and since he didn't have a spare cluster, couldn't swap to test for that. I personally purchased a salvage cluster, removed the battery terminals, installed it and it came to life (I'm also having to buy replacement connector housings because mine disintegrated). The problem is the info screen pretty much scrolled through a variety of issues like oil pressure feedback, temp feedback, fuel feedback, etc. The oil pressure gage was also unresponsive. I expected the odometer to be wrong, but didn't expect all the errors. I also started the car and while it ran, it did run rough, sputtered a bit. Do I have a bad salvaged cluster? Does the cluster need to be programmed (beside the odometer)?
