How common was / is the LSD on 993s in the UK?

Thinking of a C2 and an LSD would be useful. Any 993 owners or traders know if they were rare or common?

Cheers

Standard on 4S and Turbo, not sure about C4, i thnk i've seen a C2 or two with them but i wouldn't say it was a common option on the standard C2.

Of all the C2s I looked at only one had it.

Guess it would be quite pricy to retro-fit. Is it even possible?

I think retro fit is possible, and if so you would probably go the Quaife or Guard LSD route. I'm not a serious track junkie, so I would be happier with finding one with it as standard.

not expensive in labour to retrofit, 993RS's have only one common ailment that i am aware of and that's the LSD, i believe the parts involved are about £1000 but the labour is just a couple of hours or so.

Is the LSD option code M224? Anyone know?

Nope M224 is ABD - Active Brake Differential, a sort of traction control arrangement

220 is Locking Differential

and

221 is Porsche-locking differential

And no I don't know what the difference is, I just do the copy typing ...

PS and as I've got the list out I thought I'd include my special favourites from the options list:

780 Remove safety certificate

closely followed by

M484 Symbols for controls (sometimes Porsche just make things too easy!)

As a matter of interest, does anyone have experience of an LSD in a 993 for road rather than track use?
I understand the benefits on the track or rough stuff but my experience in other cars fitted with an LSD is in normal road use much more sliding around occurs, particually when pulling out of a junction, say, at an angle. With the 993 without a limited slip, it just goes.

Thanks Tertius. Option sticker for my car lists 220 & 224 - so guess it has the LSD?

The only prior experience I have of a LSD is a Quaife in a Corrado VR6, a car that does remarkably well (for a fwd car) without a LSD. The quaife makes a difference in the wet pulling out of junctions/negotiating roundabouts - it puts the power down alot better. You can get on the throttle earlier.

No idea of it's effects on a 993 as assuming my car has one I haven't driven another 993 long enough to know the differences.

I read somewhere a while ago that the standard 993 LSD is not up to Porsche's usual standards (for LSDs) and that it doesn't have a very long life. I've just found some notes that the recommended (from a Rennlist guru I think) LSD is not a Quaife type, is best used with 996 GT3 plates and is said to aid braking as well as acceleration. Sorry I don't have any more information. Retro fit would be about £1000 ish. Anyone else?

Short life for sure, especially with track use. I've heard of rebuilds using Porsche Motorsport bits, or swapping to the PM LSD. Many Rennlisters are popping for the Guard unit.

A good LSD will give better stability under braking ..

cheers, Maurice

I had the diff plates replaced in my previous 993RS with motorsport plates (nice work Russell), it made a world of difference particularly putting the power down on a wet track.
I understand the atandard plates rarely last much more than 30k miles, as Maurice mentioned track work will reduce the life expectancy further.
