LSDs

I'm going to fit a LSD to my 968CS.

Is it best to stick with the Porsche OEM part or one of the more modern aftermarket diffs? I have been quoted ~£1,000 for a carbon LSD

Thanks

On other forums I gather it is better to go for an aftermarket product. Cheaper than a Porsche LSD, last longer, more robust, easier and cheaper to rebuild, and you can configure to suit your own needs. There is a company called Guards Transmissions and a chap on the 944 forum (Pat, 333pg333) has an LSD from them and raves on about it. It's something that is definately on my wish list.

Fraser has a carbon LSD fitted to his SC 968 and I think he is very pleased with it. I am with Scott and would
fit an after market one not a Porcshe one. Mind I know where there is a 2nd hand Porsche one if the price is right!

EMC in Birmingham have fitted/supplied a good few KAAZ lsd's now, they have been used successfully in 968 race cars. As you are in Worcestershire fairly local to you as well. Talking to Kevin only a week ago he was raving about how good a quality product the KAAZ diff is. I believe Paul Follets race car has one for example.

You have a few options on diffs.
There is the Porsche "plate" [LSD] diff.
The Porsche "torsen" [torque sensing] diff.
Aftermarket jobs,,,,
The US versions [Guards transmision] although these will now work out pretty expensive due to the exchange rate.
"9M" carbon diff..
Kaaz diff [plate type] EMC in brum...
Or Quaife "torsen diff" ..
My recomendation, after having driven cars with both plate + torsen diffs, would be to get a torsen...
On the fact that the plate type can be a bit "agressive" when cornering. They tend to "snatch + grab", if you get my meaning....And around town / trafiic can be tiresome...Although on track the plate diffs are FAB....
Whereas the torsen type have none of these trailts. Just smooth transitions...
Also the plate diffs are usually locking in both accelleration + decelleration
Whereas the torsen are only in accelleration...

PS i hope i havnt just "tought you how to suck eggs"..???

Hope this helps + you get fixed up..???

this is a great help, given that the car will mainly used on the road, the Torsen sounds like the best option.

Do you have any recommendations as to who can supply and fit Torsen diffs?

Thanks

David

Quaiffe and Guards both do Torsen diffs, so I would start with thier web sites. Any good independant should be able to fit it for you. I would find one with a good reputation for re-building gearboxes though as you only want to be fitting it once.

Hi David - as Peter said, I've got the 9M Carbonetic LSD fitted to my car - and jolly good it seems too.

I had a load of other work done at the same time - motorsport flywheel, clutch, pinion bearings (eeek!) so overall saved money in doing the whole lot in one hit.

Also as Peter said, get the work done by someone who does a good bit of gearbox work, and you may save time and money in the long run.

The carbonetic diff is good inasmuchas you can change the plates to achieve whatever effect you want, and being carbon it becomes more effective the hotter it gets, apparently.

If you want a run round the block in mine, let me know.

Cheers,

Fraser.

I was looking at a Quaiffe brochure on THursday and it's very comprehensive --- looks good stuff --- any user comments ?

LSD fitted today, decided to go the KAAZ route with EMC, who also gave the car an annual service. Very nice people, excellent service and good value for money - highly recommended []
