Wow! You must be on their first call list - I haven't even heard they were working on a LSD. Congrats!

Congrats! the LSD is not even shown on the website. Any pics of it?

Nice, was wondering when we would see this come out.

So first impression, the response time between pressing the gas pedal and power to the wheels is so much faster. Actually, Dinan recommended this LSD for RWD 550 to handel the additional power from the mods (stage 4) There is way too much power for standard differential=wheels slippage and then power reduction from traction control under WOT especially in corners. Not an issue with the Xi models. The LSD ensures that all that power gets put to the ground.

Very nice. Their intake is next to be released. I've seen it up close recently. How it integrates with the braces in the engine compartment is beautiful.

I am very interested in the CAI, specifically if it provides real world gains. I debated the other modifications past the Stage 2 flash but they seem to have fairly minimal returns for the extra dollar (although the exhause does certainly sound better than stock).

I will be very interested in the intake. Is Joe planning on putting it on his beast? Would love to check it out up close.

Any idea when they will have it up on the website with details (pricing)?

Is this a RWD only mod or will it work with xDrive? How much was the parts & labor? Thanks!

This is RWD only.

Correct RWD drive only. Parts about USD 3 k after the 15% Dinan disc. about 4.1 hrs labor

The LSD is up on the Dinan site: Dinan F10 Limited Slip Differential

tjiangi,

You made no mention of the core exchange. Hopefully you are aware of this cost savings.

The website also says that it is xDrive compatible. I wonder if that is a mistake?

Is the $3k after the 15% discount and after the Core exchange? My local Dinan Dealer still not sure about the Core exchange credit.

I'm not sure if I'm reading this correctly, but I emailed Dinan regarding the credit, and what I gathered was the diff is $3600 regardless. If you decide to keep your diff, it's a $2200 charge on top of that. I thought the diff was $3600, then we are refunded the core charge ($2200) so we only pay $1400 for the diff after it all. Guess I was wrong, haha.

The price listed is for the differential. The core deposit would only come into play if you were purchasing it directly (not through one of our Authorized Dealers). The core deposit is in addition to the price of the diff and is refunded when the stock differential is returned to us in the same manner it was paid for. Again, if you are buying through an Authorized Dealer, you would not need to be concerned with the core deposit at all.

It is a wonderful upgrade for the F10 550! You’ll see faster acceleration and greater torque to the ground during corner exit, increasing exit speed. No more inside rear wheel going up in smoke!

Best regards,

Scott Leandres

Good Ol' Dinan it seems like everything they offer has to be $3k+.

That's a bummer, but I'll admit I was bit surprised when I saw the core exchange and thought it was discount on the total price.

It would need a 3.08 ratio to be compatible, but unless one plans to use a 550xi for snow-track racing, it has more than enough traction.

This is a key component. I think BMW should have had one of these as standard to have the 550i be competitive with the S6.

I've said this before, the LSD M-differential is maybe the most surprising part of the M3. Much has been written about the engine, handling, steering etc and you expect them to be phenomenal but the differential isn't as sexy to write long stories about so for me it was the one thing that took me by surprise and totally blew me away. It makes the M3 the perfect Seattle driver's car. The wet weather performance is simply superb much due to the LSD. Great upgrade tjangi!

That is correct, thank you for pointing it out.

Would you please explain what is a core exchange. I know that the fly wheel on the stock diff is welded, how can the dinan lsd be bolted in if the stock diff is welded in. If there is a solution to this I will spring for the dinan lsd. In the past I had changed out the stock diff on my 335i, but that was bolted on and the change was easily done and well worth it in performance. BMW is now welding their stock diff to stop this trend. Hope to hear your response. Thanks....

Welding on a diff? That doesn't sound right....

And there is no flywheel on a diff....

Here is the stock diff. Clearly shows two bolts.

The picture of the stock diff is the pumpkin, within it is the differential. The differential is welded by BMW into the pumpkin and not bolted on... In order to remove the stock differential one has to open the pumpkin and cut out the stock differential from within and that is a difficult task. It used to be that BMW bolted on their differential into the pumpkin and it could be easily removed and replaced. So can anyone please let me know what is a core exchange... Thanks...
