Clutch type LSD for the 135i DCT?

[katsooba]

Hi guys,

im currently in the market for a LSD for my 135i DCT
but seems there arent any options for the CLUTCH TYPE lsd.
i am interested in the 1.5way LSD and not the helical quaife\wavetrack\mfactory lsd.

Been eyeing the Kaaz and OSG but to no avail.

are we realy stuck with the helical lsd options?

DREXLER Clutch type LSD ; BMW uses this in DTM, Motortsports cars.

Performance Gearing as well. Few have it on the e90 forums

dont the drexler units go for something like 5k$? thats a little steep.
i would love to have one, but cant afford that.
i was looking at something like 1500-2500$.
seems other than them no one makes a cluth type diff for the DCT.
that is kind of odd to see since our bimmers are THE cars for this clutch type application and not needing a helical diff like most FWD cars.
hosently having a torsen diff just to say "i got an lsd" is not the way to go here.

MFactory Hi

i am not underestimating the advantages of the Helical LSD
but after having taking a spin in a good calibrated 1.5 way LSD i feel that it realy suits me more thank to its more drifting attitude.
if not that, i would be all over the Helical LSD.

[katsooba]

sorry if my wording was out of context

i think that our bimmers deserve to have clutch type LSDs, not only for how they act, but its the heritage balls out sideways in any situation.

i guess the only current option is a 5k$ drexler unit.
need to get them by email.

MFactory,
what is the locking characteristic for a Helical LSD?
when power sliding or drifing, wont the power keep transferring between wheels all the time?

If you've been out in a Plate type LSD and find it suits your driving style better, then that is what you should probably get. However, as you already know, there are not too many DCT fitments available at the moment unfortunately

Hey MFactory,

What would be the difference between the Quaife diff and your diff?

[katsooba]

so.. had a chat with Drexler, no 2.56 final drive ratio for the DCT guys,
only 3.15
i guess that is out of the equation

[aloksatoor]

Thats great to hear Mfactory, will the number of plates/locking % be custom?

That is the best news i heard in a while!
consider me sold.

keep us updated on the PLATE LSD!

anywhere to read about the specs?

[katsooba]

@MFactory i noticed the change you made to the MFactory website,
looks good!
i noticed that there is a 2.56 helical LSD already instock for the DCT model 135i but it says mainland US only, what does that mean?

does this also mean that a plate type fitment would come very soon?

[katsooba]

keep us updated!

If you're interested in a plate LSD go to Performance Gearing or Diffsonline and you can get one now. No need to wait.

The site is being updated but Jim builds BMW diffs to spec and really knows his stuff. I have one of his diffs in my e90.

HeelToe,

thank you for the info,

as for diffsonline, i would think that MFactory could give us some more competitive offering,
and about Performance Gearing, well, i hope they updates their website soon
