Good Morning guys. Since learning or reading here that the upcoming m240i won't be available with an M performance LSD, I am curious if this will help persuade people to hang on to their m235i if it is equipped with one. I realize all the hype about the new motor coming out and it definitely seems like something to look forward to. However, I am wondering if anyone is feeling more inclined to keep this one now. I have heard many guys on here comment about putting different and better LSDs on their cars, so I am aware there are LSDs out there that are alot better then the one I have in mine. Does this help or make anyone consider keeping their cars more so now?

Since the LSD was no longer available as a port installed option when I ordered my M235i I just ordered one from Sun Motors BMW and had it installed locally. I suspect that you could do the same with the M240i. Just make sure you get one with the correct gear ratio (there are currently two ratios available). If the correct ration isn't available just wait a year or so and the LSD will eventually be in production.

The last time I checked, there was only one gear ratio for both auto and manual M235i's. IIRC, it was 3.08/1. What other ratio have you seen?

[mdputnam]

Same differential different ratios.
33107555607 For the 335i and 435i Automatic transmission 3.15/1
3310xxxxxxx For the 335i and 435i Manual transmission 3.23/1
33108659987 (or the old part no. 33107555610) For the M235i 3.08/1

Probably.

Either keep your M235i with an LSD, or get an M2. Those seem to be your only options if you want an LSD. Go figure BMW won't put an LSD in the M240, they're trying to make a bigger gap between the M240 and the M2.

I put the LSD in my car because I knew sooner or later BMW would cut the program for it; Whether it be because M2 or because of available parts. I think M235i's with optioned LSD's will probably go for a little more than cars sans-LSD in the coming years.

That's something else I was wondering. I lease, and have bought at the end of my lease before. I have mine a little over a year and only have 6k miles. Figuring with the LSD option and the low miles it may be worth keeping. Combined with the Dinan spring setup and the LSD, the car handles and rides awesome.. M2 of course is also under consideration, granted the lease isn't completely insane. Which I'm more then sure it will be.

What were you charged to put the LSD in?

I'm saving to get the M Performance LSD for my 16 M235i Coupe.

I was quoted around 1k from 2 different dealerships here in Houston. They said it is like a 5-7 hour job.

Not sure if its true or not.

[Killramos]

1k all in? If so that's literally the cheapest M Perf LSD install ever.

MSRP for the part is $2,370 USD.

I think I paid 700 CAD to have mine installed ( back when CAD was about par to USD ). I believe its a 4 hour job according to BMW but shouldn't even take that long. its a 1 to one part switch with no software changes.

As for if the part is important? I think if it isto you, you are probably knocking on M2 territory anyways, I certainly would have paid the like 4k or whatever it is extra over what i paid for mine to upgrade.

I doubt my LSD will make a difference on resale except to the right buyer.

1k labor he means

I would think LSD does make a big resale difference, obviously not 3-4k but I did end up paying extra to for my car because it has one installed

[Wreckt]

It was 2,050 USD for LSD + Associated Fluids/Seals + Tax
Around 1,000 USD for install

Total Out the door price= 3,050 USD after tax

I'm having mine done within the next 2-4 months.

BMW's After Sales Assistance Portal (ASAP) says it should take 2.5 hours, so multiply that by your shops labor rate. For example in Aliceville, Alabama the labor rate for an independent mechanic is around $68.00/hour. Here in only-the-rich-survive San Diego the labor rate for an independent BMW mechanic is $165.00/hour.

Do you have a source on the 2.5 hours? My service guys said 5-7. If its 2.5. I would save alot on labor.

And if you're going to buy a LSD, at least get a price quote from Sun Motors BMW in Mechanicsburg, PA (hint hint).

$1,000 for install? LORD. How do BMW shops get away with this when book time is only 2.5 hours (~$360)? I did a diff swap on my 2003 rwd G35 and it took me 3 hours doing it myself and had never such a thing before. The BMW diff installs the same way. There's nothing complicated about it.

I've never installed a diff in a Nissan but I did install the M Performance diff in my 235i and it is more complicated then previous BMW's due to the stub shafts now being part of the axle half shafts instead of being bolted. Having the special tool to pop the stub shafts out of the diff is required or you risk damaging the half shaft. Since the stub shafts are rather long it requires positioning the rear diff in such a way that you can get them out of the diff but there isn't much room to move the half shafts due to interference with suspension components. Its tricky and requires some patience, it doesn't just fall out anymore after removing some bolts.

Thanks for the response. Yes, the Nissan diff had the half-shafts bolted to the diff axle stubs which made the swap fairly easy.

With respect to removing the half-shaft and connected stubs from the diff on the m235, isn't just a matter of using a small pry bar between the axle stub and diff housing, using the cast diff housing as the pivot point, and popping the stub out of the diff? From my online research, that's what guys do to service the axle seals on BMW diffs and most every other diff make out there. On the BMW diffs, it appears that the snap ring remains inside the diff carrier rather than on the stub, thus making removal of the stub fairly easy (i.e., not a ton of force is needed to unseat it from the snap ring in the diff).

What parts did you replace when doing the swap?

How easily does the axle stub reseat in the diff?
