wow I don't feel any smarter about the subject...
So here's what I'm hearing: OS Giken Multi-plate or the M-Factory torsen?

If you want to go Plate, yes, that is my recommendation, however, do some more research on the LSD first, especially if you are making a lot of power
If you want to go Helical, then you have 3 options to choose from. All 3 are good choices, with the Quaife being the most basic, the Wavetrac offering it's patented wavelock, and the MFactory offering the most torque bias |

They still have the spider gear issue or whatever it turned out to be?

I actually wanted to get one, and a friend/person within the OSG company told me basically they will sell me the diff if I really wanted it with no attached warranty, but they didn't recommend it...and pointed me towards Dan and my now diff that has been flawless for a year and a half. Don't know if the warranty is still true, but I'd be nervous. |

Basically, unless they redesign the whole internal layout, this issue is not going to go away with any high torque application. |

Most LSD's on the market that are offered by a Manufacturer/Company (instead of a builder/tuner/shop): MFactory, Cusco, OS Giken, Kaaz, ATS/Carbonetic, Drexler, Titan, 3J etc etc

And you're saying the diffsonline is OEM-based? Just trying to get my facts straight. I've found your posts very informative Last edited by chris82; 05-26-2016 at 11:52 AM.. |

Quaife is a Torsen style LSD (i.e Helical). My recommendations to the OP above was concerning Plate style LSD's.
The majority of Diffsonline builds are with his OEM-based LSD's, yes. However, he does sell more advanced LSD's, but are a lot more expensive than his regular bread-n-butter builds. OS Giken - Adjustability-wise, this is the most advanced, but as mentioned in a few posts above, they do have their issues on high torque applications Drexler - This is the most popular LSD in Europe for BMW's, but is very expensive, especially if you want more adjustability from their units. If budget is no option, this is, in my opinion, the best choice at the present moment We (MFactory) do have our v2 Plate LSD's currently under development, which was designed from scratch to be the most adjustable, can hold high torque and come in at an affordable price point. However, we don't have an ETA on this yet, so I am not adding it to this list. Last edited by MFactory; 05-26-2016 at 12:02 PM.. |

Or will the MFactory v2 Plate have some limitations, drawbacks or be missing some features compared to those two brands' offerings. |

Yes, we designed our new v2 to be the most adjustable (pre-load, ramp angles, lock capacity. All can be adjusted by the end-user without having to order new parts nor send back your LSD), stronger materials (to avoid the same issues that OS Giken were having), our 2nd Generation Active Friction™ Plates (originally developed for our competition Touring Cars) which reduces NVH by as much as 50% over regular steel and/or sintered plates that the competition uses, and, of course, our industry-leading globally transferable lifetime warranty
If you are in the market for a new Plate type LSD, I would suggest looking into our new option As this is not a sales thread though, I cannot give further information with regards to pricing, so you would have to PM me for more details. |

I agree partially on not running the gear type LSD on the E8x E9x chassis. For street/track they are fine and likely never need rebuilding with minimum maintenance. For serious track and extreme street the clutch type is preferred. This type will require more frequent maintenance and rebuilds. As for getting the car balanced, more front camber and bar works well. |

Do you have something else in mind? By the way, in addition to Turner, I think Bimmerworld and BAVauto also source from Dan, not to mention the shop I use.

Yes, all of Bimmerworlds diff's are built by Dan.
Regarding your "more frequent maintenance and rebuilds" question, you won't notice it so much on your current purchase as you purchased an oem-based build, so this very tame in terms of features/performance compared to an aftermarket Plate LSD. Not all Plate LSD's are the same. oem-based LSD's were designed primarily for the street car, not the race car. Suffice to say, you will probably notice better performance on the street car with a Helical LSD than an oem-based LSD, as the only advantage that the oem-based LSD has over the Helical is if you un-load one wheel (which won't happen on a street car). |

OK, thanks. This is mutating into track car. And I do like riding the kerbs, with unloading on the return to earth.

Why do the plate-type diffs require so much maintenance? To compensate for wear on the plates? There are also lots of people using those types of diffs on drag/street cars, but they're not that high mileage, so maybe that's why I haven't heard a lot of maintenance being needed on them. I'm guessing it's not strength, as I'm putting 1000 ft/lbs through one in my race car (and driving it to meet-ups). It works gloriously well, and it locks hard enough to launch the car straight as an arrow with both front wheels off the ground. |

The Plates on the LSD only wear when they slip. As you are Drag Racing, the plates don't get the same sort of "workout" as they do with circuit racing. Similarly, a street car will not require as much maintenance as a dedicated race car.
You have 1000lbs? What car, and what LSD? |

Not BMW yet ... I'm lurking around here learning before I get a 1er for a daily driver ... This is the car, it's a blown, intercooled, alcohol injected 383 with a faceplated Tremec TKO 600 5-speed, a Spec 11" twin disc clutch, and a moser rear end with 33 spline axles and an Eaton super posi diff. I've blown the teeth off a few ring gears and the diff has survived (second picture is more recent). |
