Best LSD

katsooba · 05-12-2015, 02:16 PM

what is the difference between the EU and US gear specs?

MFactory · 05-12-2015, 02:18 PM

AU/EU 135i pinions use a different propshaft flange, so the pinion ends are different.

Does not apply to 335i's

You could always swap over to the 335i driveshaft flange, which would solve the issue.

I assume that's a cut and weld job though?

MFactory · 05-13-2015, 05:41 AM

No, as you have a 2pc propshaft

katsooba · 05-13-2015, 08:33 AM

so if i own an European 135i DCT
does it mean i cannot purchase the ring+pinion from MFactory?

kind of confused now

MFactory · 05-14-2015, 12:10 PM

I believe the DCT may be different, but I will double check.

Sorry to be pedantic, but do you know of anyone who has done this? Any further details on the actual parts I need?

I would buy an LSD and new gearset tomorrow if I was 100% confident it would fit.

toro_cba · 08-23-2015, 08:59 AM

How would I know if my car is EU or USA spec, I`m in south america, usually we get euro specs but want to check before buying.

MFactory · 08-23-2015, 11:54 AM

From what I've found, the 135i DCT does not have the same issue as the EU 135i MT.

thanks for the link

I did a M3 conversion on my 135i, frankly unless you are MT and can get parts very cheap, dont do it.

Could you elaborate a little more?

Traf · 06-19-2017, 03:02 AM

The stock M3 unit is not worth it if you have to pay a lot for it, it is unpredictable, the pump mecanism wears over time and you get a lot of play in one of the output shafts.
It is worth it if you have a welded crown on your current diff, because of the cost conversion to bolted.
Otherwise go for a wavetrac or mfactory.
Of course if you want some real diffs options, then go for the M3 diff and upgrade it later to a real LSD, but that is going to cost you.

Updates?? New or revised recommendations? Reliability? Ratio recommendations?

Also interested in this. Anything new in the last 5 or so years on LSDs, any new/different opinions on best for the money for a mostly street driven car that loses traction too often?

Running a Quaife in mine, no issues and looks killer with the VAC Autosport finned diff cover.
