Out of all the benefits or characteristics I read regarding an LSD, something I had not expected was a difference in the way the engine sounds on accelerations. More "angry": when before it was more of a loud "hum", now it's like every piston stroke can be heard more deliberately. At first I thought it was just me, but my girlfriend noticed it too when I took her for a ride. The only thing I can think of is simply that the difference in the feeling of grip changed the way in which I am applying throttle. (Of course this is just a function of how I react to it, as opposed to a feature of it in itself) Had a word with the head engineer over at the BMW dealership regarding coding: He said that no coding was necessary during installation as this was a mechanical adjustment to the car that did not concern the electronics. I did not want to press him on the issue, after all, he's the expert and I'm not. Left me wondering though, given what I've read in this thread. Last edited by Aberle; 01-12-2019 at 10:32 PM.. |

I recently drove a 340i ZHP with the LSD standard, the first thing I noticed was significant harder pull from stop to 30 MPH and the better acceleration coming out of corners where my 335i MPPK standard axle breaks loose way too easy or starts to lose grip on any imperfect surface. I was debating putting a LSD on mine or just taking the plunge on a new ZHP. That being said, I could hear the sound being deeper after your install, because the traction would be much better, thus not activate the traction control (instant de-tune to keep from spinning wheels). Which LSD unit did you get? who did you buy from?

I got the M Performance LSD, part number: 33108659989 I bought it from Theis Motorsport. Bought the MPPSK from them as well as a couple of other items (pedals/rear diffuser), very good service. You'd install it yourself? If so, would you consider making a video of the process? |

Hello, I have installed the OS Giken LSD from Japan at Hardeman Motorsport in the Netherlands. It's the best upgrade on my 2016 440I with MPPSK. They also replaced adaptive m-sport suspension with the Öhlins Road & Track kit and i love the combination. Best mods for my car sofar. Understeer has gone, only when you do engine braking, then the LSD is adjusted to limit to about 40 % and you get safe understeer. Going on throtle midcorner creates a good controllable oversteer.
And indeed there is no need for software adjustments. Due to the LSD the need for corrections by the ESP is less. |

Thank you for confirming that bit regarding (no) coding. Awesome! I'll be checking your thread for updates. Ideally yes, but according to the dealership I am one of only two owners of a 340i in my country thus far. When picking out the LSD online, I ordered one that "seemed" to match, but was quickly told by the store that I required a part number specific to my 340i, so I have no one to sell it to. This might change with time as I heard they might be bringing in some this year. So just as is the case of the stock exhaust when I had the MPPSK installed, the "old" diff is sitting in a closet awaiting the prospect of becoming a decorative item. |

The OS Giken is a visco type lsd like the MPerf lsd. But it has a lot more discs in it so it is much more robust and needs less to no maintenance. Before install the the technician can adjust the % for accellaration and decelleration

There's a bunch of F80 eLSD available Is it impossible to make it work in F30?
I expect nothing to be in common in the rear with F30, but maybe someone has done some research. |

Last time i checked the subframes are different so the physical housing doesn't bolt up to our cars.

Using the M subframe and arms will give an increased track no doubt. Might need to compensate with wheel offsets. Next step is a custom propshaft. Not as easy as you think, the splines are different on the M diff, even though the connection method is similar to that used on x35i cars. Carbon m prop but length changed to suit, or perhaps easier is the layer steel m prop. Finally, you need to figure out how the diff is controlled and mimic that to make it work. All in all it seems a major project to give gains that you can achieve by fitting a mechanical LS diff. |

340 xDrive and LSD?
Has anyone done the M Performance LSD on a 340 xDrive with a manual transmission?
I ordered the correct part number per the BMW site and confirmed it with the Parts manager before I ordered the part. Now it appears the part that was received does not fit my car. The car has been at the dealer for a week now, waiting for BMW Corp to get involved on what actually fits my car. The dealership believes the part that was in the box was miss-labeled and is for an automatic transmission car. So i am curious if anyone has done this LSD on an x-drive manual 340. Thanks |
