That's pretty bad when others are getting 32.
It also puts excess wear on the engine.

Damn who is getting 32 mpg in a v6 on the highway. I feel happy when I break the 24 mark on trips. But I do have a 330

I average 22-23mpg around town and 30-31mpg on the freeway with a 330i. 26mpg is pretty bad.

Its not a V6 it is an Inline 6 and 24 is pretty shitty if you are just doing freeway driving. Looks to me like you have a lead foot.

I'm over hauling the motor in 2 weeks so hopefully my mpg goes up. Going plugs, VCG, Vanos. Oil filter gasket and oil line. Also a few performance mods

Idk who has a v6. I certainly don't. It's an inline.
I've averaged 34 on a 600+ mile trip before. If I don't break 30 mpg I'm disappointed.

Can you quantify this? I've had multiple four-cylinder engines in the past, all of which spun around 3500rpm or higher at the same speeds, and they've all gone past 200k. Modern day lubricants make this a thing of the past, IMO.

Also, I should disclose that my other cars are an E28 535i and an E12 528i, so when I tout my 26 mpg number as good, it's in comparison to those other two, which never get above 21.

M-LSD isn't viscous in the traditional sense... And I still haven't found any evidence I premature failures on primarily street driven M3s. Even Obioban's running the factory LSD, and his M3 leads a rougher life than almost any out there
I'm with you 100%; E30/36 LSD is already avail- Most people cannot afford it or don't feel its worth the cost to them.


I agree that very few street guys (98%) really cares about lap times (or honestly need a LSD); if they really did they would be ordering OS-Giken units like the GTS-4 guys love to.

The e30/36 LSD has been proven in e46's internationally with stock power and ESS supercharger/ TRM turbo setups; my billet unit went fedex air to a ESS m54b30 car in Malaysia. These ZF retrofit LSD units are built by many; you can pick from Metric mechanic, Diffs online, me, others.

I would not call the expiry of m-variable units "premature"; I think 80-100k miles is plenty of service life of a clutch type LSD with viscous activation - attached to a S54.

Even a e36M clutch type LSD attached to a S52 engine is pretty much expired by 80-100k miles; Nobody with M car (including myself) is at all nice to them. I have personally melted quite a few E36/e30 clutch type units to the point of being open units and 1 wheel wonders.


I have replaced more than few M-variable units; would be more than happy to send you a melted one for $free to play with / dissect - expired units smell really terrible when expired compared to just terrible for non-expired units.

a couple recent expired ones brought to me by local customers who say they are expired and 1 wheel wondering:

440rwhp on VF supercharger +meth = melted M-variable (100k miles)
My endurance racing team mate + big tires+ footwork bolt on e46M + street use = melted m-variable. (98k miles)

I fedex-air shipped a built complete differential from Northern California to Promotec ZA in South Africa; Shipping was $1435 including customs duty of ($235)

shipping 100lbs of Iron from EUROPE to USA would not be cost efficient or affordable for most -

Quality is also of concern; if everyone else stateside known for LSD units is at 2k for a built unit in case and you found one for 50% of the par price......................the economic market forces create competition and prices drop when there is technological or operational efficiency. LSD was designed back in the early days of automotive driveline and nothing manufacturing is new under the sun.

.... I guess you'd all be pretty disappointed in me if I said I got 17 MPG... Only slightly better than my dads E92 M3.... but that might have something to do with how I drive. THAT BEING SAID. I would definetly be interested in one of these new LSDs. So long as they're cheap I'm in. Sub'd.

I can get it shipped from the UK as a gift for around 270 dollars

Wanganstyle: you retrofit e36/e30 LSD units into e46 housings? Do you sell these units? I want a LSD at the cheapest cost I can get it but do not need anything advanced right now. Just basic lockup so I can actually power out of turns. I know you can get good e30 LSD diffs for under $300. If you do sell these units, how much do you charge? This setup would be ideal for me because I prefer my stock 2.93 ratio.
The guy from Europe does the same thing (e36 LSD in e46 housing) but will not ship.
I probably have a way of getting it here thanks to a gracious offer (won't post it so you don't get hit with requests) but if I could avoid the trouble and shipping costs I'd much prefer it.

I will say that out of all my Performance parts, the LSD was one of the very best mods I did.

Going from from a Bimmer that does not have a LSD, & them getting an LSD installed; All I can say is the smile factor is incredible !


Buy a LSD, you won't regret it.

Good luck.

absolutely no communist items inside:


Yesterday I sliced open a prototype for sample/show off. Cost is a little less than a wavetrack for basic setting 2 clutch disc internal unit. Custom everything options are avail just like any other older car LSD build
