Asked if I brought in a new LSD and he quoted me 4 hours (~$100). thinking about $1700-2000k for the LSD diff...

So $2100-2400 for the LSD or $1000 for used, stock???

should I bite the bullet? Is the LSD that much of an improvement? what would you guys do?

Buy an M3.

well i admit i may have come off rude. but the thread had already touched on the point that HP does not matter in being able to benefit from a Limited Slip Differential. then you posted something to the contrary. thus my frustration of "two steps forward, and then three steps back". if you're going to promote your theory of needing to be over 100Hp over stock and/or a manual needing a LSD i'd gladly point out all the reasons and cars that dismiss this thought. but i'm sure since you "no" 1000HP race cars and LSD you know enough that is was a misunderstanding in your post?? if not i'm always willing to hear and maybe see a new idea and reasoning to something already learned in my decades of building cars. i'm always open to learn from others if that's the case.

for what its worth, i personally installed LSDs in several of my BMWs

Power had very little to do with the usefulness of an LSD. My first BMW was a bone stock E36 318is with an LSD, and that thing could take corners faster, go through rain and snow easier and do just about everything better than my second 325is could because it had an open diff. There is a DRASTIC difference between an open and limited slip diff, anyone who says otherwise is kidding themselves. Open diffs give you less feel of the road, less control over what the back of your car is doing. I would definitely put an LSD in my 330 if it were cost-effective to do so.

On the topic, anybody know anything about these? http://bavauto.com/shop.asp

They wanted to do a fresh seal on the new diff. Some kind of special sealing material, not the green paper seal they used to use. Based on your advice I think I'll just have them swap the fluid in the new diff and have it swapped out. Then done.

BMW doesn't make the paper seal for the diff cover anymore. As you mentioned, the shop would use a rtv silicone sealant to reseal the cover, this is cheap and pretty quick to do. I did it on mine when I installed the 3.46.

As katu said above. BMW stopped making the paper gasket for the diff cover seal. So it sounds like they want to scrape the old one off and seal with rtv. Which is basic stuff any garage or diy'er could do.

Exactly, power does not mean one can't benefit greatly from a LS Diff. Contrary to another's post.
Another simple example is from bmw's lineup the 325es, '91 318is.

I found that additional power just magnified the benefit of a LSD. I installed the OS Giken several months BEFORE the AA/2 SC kit was installed. I did notice a difference in cornering (even on track days as well) but not significantly enough to be worth the LSD's investment, IMHO. When the AA/2 SC kit was installed THEN I noticed a BIG difference in cornering, especially under power. This is why I posted at the beginning of this thread that a power increase would justify a LSD's cost much better. YMMV

Been follwing the LSD threads - where is the best deal for a Wavetrac LSD for non-M? Aware of a group guy going on for Wavetrac?

Thanks.

Doesn't an LSD make it possible to do doughnuts and drift as well?

Well the short answer is no, but it can be done using an m3 tranny, driveshaft, and output shafts. Which probably would be too cost prohibitive for what ya get.
