Cheapest LSD?
I know LSD's have been talked about at length. I was just hoping to get some clarity on what the most cost-effective way is to get an LSD, regardless of make, on this vehicle.
I have a set of Ohlins on the wayso an LSD seems like the logical next step. |

Give Turner a call, you can even choose your ratio.
https://www.turnermotorsport.com/p-3.../?pdk=AQIBAQEB You didn't ask my opinion, but having upgraded many of my past and a current car with limited slip goodness, I don't think the F22 needs it. It might help shave half a second on a lap time, but is that worth $2K plus? Just thinking about all the sticky tires or fancy wheels one could buy... |

The turn right out of my street is at an incline, for both entry and exit of the corner. Every frikkin morning, the traction light goes off, no matter what driving mode I'm in, and I'm spinning the right rear. I've got the whole dedicated winter tires+wheels thing taken care of, but I don't think that's enough to safely get through the turn without endangering myself and pissing off oncoming traffic. |

Call Brian at Sun Motors BMW. The cheapest route is the M Performance LSD. You should be able to get it for under $2K. The custom build options will cost you $4K+ which is bonkers.

Yea, I agree that it's probably not worth it. I think the thing is that this car, sporting a 300+ hp engine and an 'M' badge, should already have this basic performance feature, and really bothers the hell out of me. This car not having an LSD is like going out not wearing any underwear. It probably isn't going to have any sort of affect on anything, and you only notice it when you think about it, but in the back of your mind you know you should be wearing some.
Analogies aside, I think $2k is the most I would even start considering it. There is a lot of other juicy goodies that can be had for that money, goodies that you can really feel. Can it really be considered a safety feature? I'll be moving to Seattle soon. With all the precipitation there I could use 'safety' in order to justify it to myself... |

You'll notice its effect at every tight turn, admittedly not often in urban driving though

Also, none of McLaren's current lineup feature LSDs... Not even the P1. They use a similar brake based system. Last edited by Sail Boat; 09-15-2017 at 08:35 AM.. |

Get the LSD, it will transform your driving experience. My friend recently installed a Quaife in his m240 8AT, and he's raving about the damn thing every time we talk, thanking me for convincing him to do it, before going FBO.
These cars don't suffer too bad from inner/single wheelspin, but when you start adding power, suspension, etc, handling at the rear end will start to deteriorate and increased requirements for the LSD become obvious. MP LSD will be your best bet, imo, because it's a sealed unit, with easy install. But Wavetrac LSD makes an excellent product, with more features than the OEM unit, and probably what I'd get if I didn't have the MP LSD.. Just my $.02 |

OP, just realized you're located in Alexandria! I'm in McLean, just a few miles away. My close friend has the MP diff installed, mine is open. You're welcome to give both cars a hoon if you'd like!
Luckily, we are both on the OE Bridgestone S001 225/245 rubber which should provide a good frame of reference. Last edited by Sail Boat; 09-29-2017 at 08:07 AM.. |

A wavetrac complete LSD is one of the best and economical LSD upgrades you can install on your M235i.

Paid ~2500 eur all inclusive (labour/parts/fluids) at my independent specialist shop (no m performance for the hybrid 3), i?m very happy with it, no maintenance because no friction plate, and car looks unmodified (on this aspect at least). Race.fi seems to have them cheaper if you?re in the EU but i don?t know if they?re reliable.
