BMW e92 335i LSD Options

Iím looking to get an LSD for my 2008 6mt e92, I think there are some cheaper temporary options that you can just put into the stock pumpkin? Iím looking for something to right now maybe for a little improvement and then in a couple months from now when I go single turbo (just waiting on parts) a proper lsd to handle the power and handling
Thanks guys! Hope to hear some opinions if anybody has an LSD or upgrade

"Lincoln locker" I think is what you're looking for. 😆 Beyond that just leave it alone. Let the e-lsd do it's thing.

This! Unless you are going to have your car out on a twisty race track, the factory e-diff does a great job of putting power down to both wheels in a straight line (drag racing). There are some big HP guys running really quick 1/4 times on the stock e-diff.

does the "e-lsd" work with traction off or DCT? can you explain a bit more of what it is? just applies brakes to whichever wheel spins more?

The "e-diff" works all the time....but when the traction control is on, when the tires spin...it cuts power to the motor.

Hold the button down for 3 seconds and it will turn the traction control completely off.....just be careful because the car can and will get away from you in a hurry with it off.

Yes... when traction control is 100% off.....the e-diff still puts power down to both tires. It's pretty easy to leave two big equal length lines of rubber on the pavement 😁

Wavetrac from Whitbread is a great option. Probably second cheapest option behind racingdiffs option. Email him for better price. The ediff works fine in some situations but it'll really hinder your driving experience when you take your car through a twisty road.

The e-diff does a decent job but keep in mind, it's not truly even an electronic LSD, it's an open diff with an advanced traction control system that somewhat mimics an LSD.

IMO an LSD is very much needed if you're over 420whp or so. Mfactory, Quaife, Wavetrac, Drexler, or M3 diff are the common ones. Racingdiffs I believe is the cheaper option on eBay that some have had good luck with.

In a straight line...it works as well as an LSD. When you can put two equal rubber patches on the road with either a true LSD or the "e-diff" setup......they seem pretty equal to me. Why spend $1,000+....to do the same thing you can do with the e-diff?

Now on twisty roads or the track when you get a lot of weight shifting around....yeah, the real LSD would be much better.

Any car with a lot of torque will spin both wheels much of the time, but I definitely had a hard time going straight and not wheel hopping especially when I had my N55. LSD is definitely a worthwhile mod even for straight line IMO

After installing a wavetrac in my car I can tell you, you aren't going to get "more" traction in a straight line. When the tires are at/over the limits of traction the car IS more predictable (after coding out the e-diff) however. My car liked to erratically walk all over the road when it was tire spinning before. Essentially because the car is pulsing the brakes on the side that was spinning more which steers the car. It also feels much more natural accelerating hard out of corners.

Not if they have an open diff.......they will spin one tire and that's it.

How do you explain vehicle with open diff spinning only one wheel in snow and leaving two tires burn out marks?

I can't.... because that doesn't happen. If it's a true open diff with no "e-diff" feature....it will only spin one tire.....no matter if it's in snow, rain, or dry pavement.

Oh I does happen. E-diff or not it does happen. Additionally since you are talking about E-diff these cars came with two different settings for it. On some early models E-diff can be completely off. Not constantly on as you said previously. Basically spin only one tire. This is probably when you was too young to know about E-diff and 335i but mine was spinning only one wheel on snow/Ice when I got it in 2008. Also was living 2 tire mark on dry. Very easy to do from a dig in MT 335i but unlikely event in your AT 335i. Anyhow, letís not steer away from my original question to you: How do you explain vehicle with open diff spinning only one wheel in snow and leaving two tires burn out marks?

Anyone who races straight line or twisty' s will tell you an LSD is better then E-diff.
Anyone!
