I've had my 996 now for about a month and the only thing I am truely dissapointed about is that it does not have a limited slip differential (LSD). PSM does not come close to making up for it. When trying to put powerdown in a corner and the brakes come on it is not a good feeling. I would rather modulate my traction myself with the gas pedal than have the computer step in and do it with the brakes.

What are my options? I prefer to low maintainance with a gear type LSD instead of a clutch type. I've used Torsen's (in my S2000's) and been quite happy. I see that Quaife makes one for the 996. What sort of LSD was offered in the 1999 Carrera? Should I look for one to pull out of a wrecked car? Order the part from Porsche? Part from a Turbo, GT3?

How will the LSD interact with the PSM?

How hard is the install?

Any advise would be great.
Thanks,
Andy

Oh, and Happy New Year!

 

No one has any experience? Would I be able to order the 2004 40th Anniversary part directly from Porsche?

 

I don't have any direct experience with an LSD on a 996 but I have been looking at a Quaife as a possible upgrade. About the only time I have noticed a need for a limited slip was low gear corners at the track or an AutoX. With all the weight in the rear you really don't notice the lack of traction without limited slip as you would in other front engine cars.

My car was optioned without PSM so adding a limited slip does not present any possible compatibility problems. I am curious to see how much the 40th anniversary differential is from Porsche. The Quaifes seem to run around $1200, and then of course there is installation.

 

I'm trying to figure out how to get the part number for the 40th anniversary edition LSD and a price.

 

Call a dealer....

 

The dealer tells me that the part is $5505 and 9 hours of installation. They wouldn't give me a part number. Seems really high for a gear driven LSD.

 

ouch...

I guess for that price I can live with PSM..and turning it off. Eeek!

 

Call another dealer.....seriously...I have had a wide range of quotes from dealers...and why wont they give you the part number?

 

I have the part number now, I had to ask for it twice. 996-332-083-00. The price of a whole new transmission is not much more than that.
I'll keep looking...

 

Second quote from Sunset "4683.00 and a month from Germany for that. Plus shipping out to you, thanks."

Looks like a pretty expensive route to go considering a new 2004 40th Anniv. transmission is 11,595!

Probably have to go thrid party...

 

maybe it would be cheaper to trade your car in for a 40th ann 996?

 

newport, you are full of good advice! Thanks.

 

Otto's Venice (Ca) is the LSD king. Or, at least he used to be.

 

How about guard transmission? I see their ads for LSD's every month in panorama.

 

I heard good things about the Quaife LSDs from my racing buddies. Why dont you call a race team with experience with this - GMG comes to mind. Not your typical everyday mod.
