I agree with you. Money per performance, I do not think there are many cars that beat m240i. However some would still want to drive a full M car for aspirational purposes etc I mean not for straight forward logical reasons

I still spent less than a new M2, to boot. I got a lot of good value in buying 1 year old CPO (full warranty 5 years), at an almost 30% discount. It got better when iND parted their shop car, and picked up KW clubsport 3-ways for over 50% off (only fit RWD/pre '16 cars), and the Brembo 6/4 piston GT kit, again at well over 50% of the cost, new. Those two mods alone transformed the cars handling and stopping ability, and the rest are simply mods to accommodate the larger changes to the chassis. This car is now far more capable on track than an M2, but most wouldn't go as far because MSRP to replicate what I did would be well over the cost of the M2.

- If you do sell your car, and can't find a buyer who appreciates the added LSD, you'll have buyers instantly on the pre-owned market. Chances are you'll get at least 60-70% back upon resale, simply because it's a non-wear item, and in very high demand. The demand will grow as these cars become cheaper to obtain as well.

The only reason I didn't get an M2 at the time was price. The M2s were opening up for orders about a month after I ordered my M235. I knew the early M2s would be sold at MSRP or markup. Most early ones went for $65k+ or nearly $20K more than I paid. My lightweight no moonroof 6MT M235 with a catted downpipe only feels as quick as the M2 6MTs I've driven. The LSD and 245 square setup make it a legit sports car now. I do prefer the M2 passive suspension and steering feel though. And the looks of course, though I do agree with you about the timeless clean lines of the M235, especially with the right wheels. With that said, a majority of my mods would transfer over to an M2. I tell myself I should be happy with what I have and keep playing with it and make it my own. Hell, most people think it's an M2 anyway. LOL

Another fringe benefit of the MP LSD is it having a "1.5 way" lock up, helps keep the vehicle stabilize during braking, more so than an open diff..

Does BMW publish your diff's percentage of lock-up during coasting, braking and acceleration - or have you found it somewhere else? (Oops, looks like Poochie knew where to find it!)

Diffsonline has a page of technical information on their site that some may find useful or interesting: https://diffsonline.com/bmw-differen...formation.html. There are other sites, too, of course - some with animations of diffs in operation, explanations of ramp angles (e.g., https://blueskymotorsports.com/index...id=20&Itemid=6), exploded parts diagrams, etc.

MP LSD just installed a little over a year after buying my M240i new. Night and day difference. Should have done it sooner! Pulling out of a parking lot and getting on it (with no traffic around, of course) is a completely different experience now. The car hooks up and goes, and rotates perfectly with throttle input. No more one-wheel chatter, no more DSC over-intervention, no more veering from my lane under hard acceleration, etc. The thing drives like an actual sports car now and has tamed any desire I had to upgrade to the M2. $2700 installed vs. a $25k+ hit to upgrade to the M2C. No brainer IMO. VERY happy with my car now.

Is LSD available for xdrive as well?
When I placed my car order, I thought I saw the LSD option. (port installed)
I don't see that option anymore.

IIRC you can run the 8AT version with x-drive config. Would be a monster off the line! And it would also help reduce the amount of front-wheel intervention when wanting to power-oversteer etc.

Modifications of cars including aesthetic and especially performance modifications increase insurance premiums in UK and they must be declared. Thus in addition to the initial outlay of modifications you have to factor in recurrent insurance expenditures. For example a stock m240i and OG M2 belong to the same insurance group and therefore a modified m240i would be costlier to insure for a person. The higher the cost of modifications the higher the increase in insurance cost. In fact a number of insurance companies would refuse to insure a car that has two or more modifications.

Even more reason not to live in the UK

Maybe the LSD could be considered a "safety upgrade" for the improved braking

I live in the UK and my insurance did go up slightly when I retro-fitted my LSD to my M235i but only by a bit i.e. $25/year or so. So it's true that 'performance enhancements' do attract an increase in insurance cover. But it's based on claim stats and owner profiles (especially driver age) and post code. 65-year-olds like me are a good profile so we don't get hit as much as, say, a 30-year-old would.

So yes, over here, the tendency is to get the car that you want as stock, and leave it at that. Mods are more the domain of under-30s with Hot Hatches and so this also tends to skew the claim statistics. It's not unusual over here for under-25s not to be able to get insurance at all, from anyone, for higher performance models.

My CF mirror replacement had no effect on my insurance premium: cosmetic changes can attract a premium, but it depends on the insurer. Mine is cool with cosmetic stuff.

And remember here there is more chance to exploit the M-lite performance: 70mph on the freeway (most people will take it to 80 before worrying about the police); 60mph on single-lane roads outside of built-up areas. On British roads, you're even more hard-pressed than in the US to really exploit the farther reaches of the M handling, so this adds to the price premium and delivery wait of the M2 as well.

I would not declare it as an upgrade. It is an OEM optional item, and they wouldn't know from looking at it that it's in there. Coilovers, etc I understand..

Reporting back to this thread after my 1st track event with the M240i + LSD. The MP LSD made the entire experience absolutely sublime! When exiting corners, I was able to unwind the steering wheel and apply throttle simultaneously, which allowed the rear end to rotate just perfectly and under full control into the straights. How good this felt cannot be put into words. Just amazing control and balance all the way through. I am SO happy I invested the money into this LSD. If anyone is on the fence, DO IT! You will not regret it. Totally transforms the car. I hated how sketchy it was before and it always felt like there wasn't enough tire. Now, it feels like the Ultimate Driving Machine.

I love hearing this type of feedback. It really is a game changing experience for the RWD cars

Well adding MPE to my m240i increased the insurance by £90/ year. My 520d insurance went up by £180/year from adding window tinting, boot spoiler and from replacing 18 inch wheel with 20 inch wheels. So for me, it is probably worth it upgrading the whole vehicle than retrofitting.

[CP911]

Does anyone know what the "30% lockup on acceleration, 9% on deceleration" actually means in this case? 100% lockup typically means both wheels are going to be spinning at the same speed and receiving the same amount of torque. However, in this case, I can't tell if it means there is a max 30% speed differential between the rear wheels or if the lockup is actually 30% of a "full lockup" scenario...

[XutvJet]

Differential.

i'm late two years later thinking about getting the LSD for my 2015 M235i

I'm about to leap too, looking for a straight M perf one, wish the Mt Laurel 20% was still going...will keep eye out

[60_Driver]

Great thread. I had lots of LSD questions that were answered here. Looks like no regerts.

[Hank Scorpio]

I know this may have been talked about in the past, but can someone tell me if it's at all possible or feasible to put the M Performance LSD on a M240i xDrive?
