how much is the parts + labor roughly for the lsd install?

My install cost $600. That included the installation of Turner Motorsport's Solid Aluminum Subframe Mount Kit (https://www.turnermotorsport.com/p-3...ame-mount-kit/).

If I had to break it down, I'd say $450 for the diff install and $150 for the subframe bushing install. I suspect the bushing install would likely cost most of that combined $600 if it were done by itself.

BTW, I highly recommend the solid bushings - they and the LSD go together like PB&J (or, BL&T, if that's more to your liking! ). Given how much you're already spending – just get the bushings, too. My 2¢, of course; others may want to weigh-in with their experience with them as well.

(For those who've been considering Turner's solid Al bushing kit, it's now only $192 delivered.)

That's not bad at all! Why am I seeing it's like $2,000 on bmw website? Lol

You asked about two costs: the differential, and the cost of installation. I shared with you the cost of my installation, but not the cost of the differential itself. My differential cost – as am I'm reaching back here, without looking it up – was around $2,250.

There are a range of differentials available for our cars. They range in price from $2-3K (that's a generalization). To see the non-BMW choices, I recommend you look at what DiffsOnline has to offer: (https://diffsonline.com/bmw-f22-m235...l#.XieoD8g3m70). No affilitation - I've just been a happy customer for a very long time.

FWIW, I chose to purchase a non-BMW M Performance LSD. I did this with the full knowledge of what the BMW M Performance differential had to offer, and with the experience of having had a variety of clutch-based differentials on different BMWs. Bottom line: any LSD is a dramatic improvement over an open differential. This is simply a no-brainer.

Price-wise, the differential I chose was not materially different than what the BMW M-Performance differential would have cost me.

I picked up the LSD for $2060 shipped. I had the dealership install it for warranty purposes, and that set me back right around $1,000, which included 6 hours of labor, 1L of differential fluid, and taxes.

I read from one of the other threads that the lowest anyone has ever seen the m-perf LSD is around $1900. Does anyone have insight on where or when you would find discounts on the diff unit?

Same, I'd bite for $1900

[Pray for Mojo]

Only time I've seen it that low is during black fridays sales. Most of the time they are $2200 or so.

The DIY install could be a bitch. They said it took two people to do the install and they had the right tools (which they special ordered for my job). They said you can still do the install without the tools, it’s just substantially harder.

There is an option to remove the e-LSD function in VO as it's essentially ABS intervention under power and it can upset the LSD's function especially in off camber scenarios.

Had mine done and it's much smoother when trying to hoon. It's almost as if the e-LSD/ABS would sense slippage on the axle from modulating the throttle mid slide/turn/drift causing the engagement and disengagement of the clutches. In any case, that weirdness is gone after removing that feature

Very interesting, curious - can you turn it back on?

For sure, just needs to be added back into the VO

You'd never want to after seeing how much better the rear end behaves. Unless of course you went back to stock..

[j2dad5389]

Holy shit y'all are talking about around $3,000 dollars in total for this add-on. Is it really worth it? I wish I could drive one with it just to see what it is like

Well worth it if you want the true BMW/RWD "sports car" experience. It actually makes a significant difference to overall chassis stability, traction and net mechanical grip.

If you could find one to test out that would be ideal for sure.. Usually you know right away when a car "needs" an LSD. I noticed right away on one I test drove, so I made sure to find one w/ LSD.

Limited slip differentials, installed, are not inexpensive, and it doesn't matter which one you choose.

This is why it's a crying shame that the manufacturer doesn't offer one...installed at the factory, dammit! . It's just a guess, but the additional retail cost would probably be something like $500 to $1,000, with the additional cost to BMW being only $200 to $300 (again, my estimate).

So, we have: cheap audio system, cheap leather, cheap differential, cheap floor & trunk coverings. I don't know if the list is longer, but what a cheap-azz manufacturer!

So here is an M235 for sale with an LSD and it is on the sticker as if it was a factory add on for $3200. See pic 23 in the ad linked below:

Damn, that's crazy. Wish mine came with it.

Also for what it's worth, I feel that the car, in particular, is priced more on the expensive end. I got mine for 18.8k miles, all the same packages/options (+ Premium Package, minus the LSD), for 25k.

Just my personal preference, but I genuinely hate the feeling of not having an LSD on a car. One tire fire is the worst. I realize most of you don't live in places where the ground is wet 80 percent of the time, but even in the dry, if you're cornering near the limits it's a night and day difference.

I believe that was a port-installed option (i.e., it was installed in the United States at the port of entry), and the original buyer paid retail for the differential and the labor to install it.

Not only that, he didn't retain his stock differential. (I might be wrong about that, but I don't think it's an option to keep the diff that was installed at the factory.) The reason that matters is that a used LSD has meaningful value - enough to warrant having the OEM unit reinstalled before selling the car, anyway.

[WolfGTI]

I was only thinking of adding it for winter weather or would this still keep traction control but defeat e-ELSD. That would be perfect.

100% agree!

I did test drive one in 8AT/RWD before starting my hunt for the MT/LSD car. I noticed it was a bit loose and unsettled, but otherwise could see the potential out of the chassis. I had my buddy drive my car back to back. It actually convinced him to buy a Quaife for his m235 as well, and that unit also works really well, actually a bit better than the OEM "Drexler" unit, imo

I think the RWD should have been standard w/ LSD just as the new M340i and other M Performance models like the Z4. I think this will be the case moving forward, from the looks of things (and thank god).

TCS works as normal, but I'm usually riding in "DSC" off mode, it's a habit every time I start the car lol. If it's raining I'll usually throw it into regular Sport mode and everything is as it should be.

[WolfGTI]

Understood - I usually ride in sport for chassis - I keep the driveline comfort, if I could get rid of the burbles I would be in DSC off mode all the time - burbles are loud with a DP and cat back.

I like the TC for rain and wintry weather.
