LSD and ABD are options 220 and 224. I'm really curious how many people who have these options actually think that their LSD is still functioning. I have been told that most of them are a 2 disc design and wear very early-on in their life. Next time your car is raised on a hoist, spin one rear wheel and watch the other. If it doesn't spin, you'll know what I mean.

Question about the LSD on the C4 -- is this functionality provided in the same manner as the option on the C2 (e.g., friction plates) or is it provided through the all-wheel-drive system? My mechanic told me that the LSD in a C4 is not provided by friction plates, but through the all-wheel-drive system.
Reason for asking -- during my 60K checkup, I asked this mechanic to check whether or not the LSD was still working and he told me that it is working as long as the awd is working, and that there were no friction plates to go bad.
Thanks!

Alon,
You beat me to the punch. As everyone pointed out they were options. Also the stock LSD wears out rather quickly. If used on the track as well it could be gone as soon as by 30K miles. I talked to my friends at Devek about this problem recently and they mentioned that the factory Porsche copper pressure plate units wear out very quickly and are generally rebuilt with steel pressure plates. This used to be a good and cost effective solution but not anymore as the rebuild kit has jumped to $800. The most effective options is the guards unit which works with real gears and not pressure plates. They are excellent units that work awesome and last long. I am looking into it for my car but I am not sure the difference will be all that noticeable unless you are on the track or you are one of these rare drivers that enjoys and knows how to use serious drifting.

I spoke with Guard yesterday about that very thing. They mentioned that depending on which LSD my car is equipped with, it may be possible to replace the discs with cost effective replacements. They also mentioned that some 993s even came with 4 disc setups (that still wore out very early). There a few things that I'm looking into for this winter:
1- Lightweight flywheel and clutch setup,
2- different gear ratios (euro-spec RS or other)
3- an LSD replacement or rebuild

By the way, it has also been suggested to me that as far as gearing options go, we are quite limited. Some rebuilders use our current 5th gear as the new 6th with other ratios for 3rd, 4th and a new 5th but I was told that the 1st and 2nd gears reside on the main input shaft and can not be changed without huge costs.
I need to drive around and not use my current 6th gear to see if I can live with 5th as the top gear ratio. I'm not too sure that will work out for me as I do quite a bit of highway driving.
