Limited Slip Differential--a MUST HAVE for '99 996 C2?

I believe the RMS issue is more prevalent in pre '02 cars - this can be remedied by looking for a car that had the RMS replaced. However, from my research it appears that some 1999 engines may have a casting flaw that makes them weaker and more prone to go kaboom. Maybe others can chime in on this, but I think that kinda makes sense given that it's a first year production car, and in general I tend to avoid first year anything on a car.

Yes...that about sums up what I've read. Some of this may be factual, others urban legend. There seem to be many MkI 996 owners that are quite happy with their cars though (shrug) ?

My local Porsche expert (Terry Heath of EuroMotorworks http://www.euromotorworks.com/ ) can install a Quaife LSD in my prospective 996 purchase for $3216--parts and labor (the GT LSD would be $4036; and the GT3 LSD would be $4339--parts and labor). Thanks!
Why not look for a 40th Anniversary, which has LSD?

Galun.... do a search. seems that 02+ cars have RMS early replacements, as do 997s and even the GT3s. BTW early means under 60K miles.
So the 1999 996 is the 1st year? In the USA/NA.. where did all the 1998 996s go that were sold in the ROW? Must of blown up.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
Here we go again. The 3.4L engine goes kaboom. RMS causes it. yadda yadda. LOL
So, what is a RMS... it is a little rubber seal that costs under $20. You just have to take the transmission off to get to it as is with most things on our cars.
Everything is hard to reach.. Even a spark plug change is a PITA in a 996 (no room).

Excellent points (you echo JimB and Paul). As for the 40th An that's some dough! I'll be saving a few years for that car (I'm a poor Bimmer owner LOL
)

I would not forego an otherwise nice car OR drop the money on an aftermarket LSD. For the few weekends you will use the car on the track, I bet you would never notice the difference. Plus, keep in mind that stock or near stock 996s tend to understeer anyway (sure you can tune it out, but still . . . ), so LSD could actually make the issue a little worse under certain circumstances.

Yes...sounds reasonable. BTW, I like your sig animation (it morphs through all the generations of 911s as you stare at it).

How about the casting flaw issue? Is that just an urban legend?

Sorry if I am testy. It's been a long week and it's Friday. Pesky developers with their bugs, pesky sales people with their deal prospects, pesky field techs with their rtfm questions, pesky customers with their feature requests, pesky analysts with their roadmap reviews. There much better.

Wait, does this mean an LSD could increase understeer in a 996? How do you tune out the inherent understeer in the Carrera (besides foregoing an LSD)?

This is a good thread that recently popped up on the gt3 board. It gives a good explanation of how LSDs work.

If you are going to put in a new LSD... guard would be the way to go regardless of the ramps. They can build what you want, the quality is much better than the Porsche part, and it cost less. My dealer price to replace mine was $3,600 for the part, guard $2,400.
For a GT3 90% track a Guard 50/80 is the way to go.
Call guard and ask them the question. There is nobody that knows more than them.
