Yes, the DCT uses speed as a reference for shifting. We're waiting back on some customers who have gone for a shorter ratio. In the meantime though, unless you have the ability to tweak your ecu tables, I would recommend the stock 2.56

Standard oem ratios are 2.56, 2.81, 3.08 and 3.46. There are shorter ratios available from BMW Motorsport, but those cost around $3k+ for the Ring & Pinion

Yes, it is the same. The oem ratio is 2.56, so you can choose either oem or aftermarket. For aftermarket, there is only 1 company that offers this. Again, I can't really mention pricing though otherwise I would probably get warned/banned for advertising ;)

1.5l is all the carrier takes. No more expensive than any other BMW rear-end (it's the exact same rear-end as that in the 135i/335i, except slightly different mounting points)

With the 35i, the ring gear is welded onto the oem differential, so to install an LSD, you either have to 1) machined it off, machined it flat, have it tapped, machine a spacer, purchase ring gear bolts, then reinstall onto the new LSD. This is a very precise job; not many machine shops can do...

Thank you for your understanding :) As mentioned though, as much as I would have liked to go into more detail into each "offering", I simply can't do that because of my username (and thus my association with one of the manufacturers). If I done that, everyone would say I'm being biased (which I...

First of all, my post wasn't an "advertisement", far from it. I'm not a sponsor on here, so I cannot advertise on here. It was simply a post to clarify between the 3 main types of Torque Biasing differentials, which I believe I have done. No objectivity at all, as it was not needed simply...

If it's a Helical LSD, these are maintenance free. No special fluids required; just the regular 75w90. We do recommend a fluid change after an initial 500 mile break-in though If it's a Plate type LSD, these do require to be maintained due to wear parts (i.e Plates). How often, depends on the...

The Quaife is a very good LSD, and I'm sure you are enjoying it with no hassles :) Yeah, installation was an issue when we first came into the market, but now that we have the facility open, we can do installations for those willing to come in, or offer core exchanges for those a bit further...

Grinspeed are MFactory R&D (Europe), our UK facility :)

By nature of its design, a Torque Biasing differential does NOT lock; it is in a constant state of Torque Biasing (hence the name) between the left/right wheels, depending on which has more traction. The internal cone washers are used for pre-loading the gears against the housing, but in real...

Our new 215 Plate type LSD is undergoing testing just now, and is expected to be ready sometime late Nov. Your only other option at present is the OS Giken or Drexler, both of which will severely dent your wallet (if you must buy now though, go for the Drexler. I would stay away from the OS...

Hey there, which dealer in Poland was it you found unsatisfactory? if you have a 3.23 or 3.46, the LSD is the same fitment. Even if it were wrong, it is only the bottom flange that is different, and we could have a replacement flange out to you in a few days. for Diff Bearings, we now keep...

Sorry for the mixup. Hope you received the replacement diff ok?
