Most of the people who will buy the 335i won't need a LSD, in fact, most of them will never even touch the DSC button.

Even most of this forum's members who buy the 335i still won't need it.

But yeah, BMW should have included a LSD in the performance package for the E46, too.

Need? I agree. But want? They can be different things. Not sure I want one 3k worth though.

I don't think they'd want it either...they couldn't tell the difference anyway.

Imagine telling someone that it has a LSD, and they go, "I CAN FEEL THE DIFFERENCE!"

Does anyone know if the 328ix or 335ix will have a limited slip rear diff?

AFAIK, no. No mechanical LSD.

Both front and rear diffs will still use engine throttling and wheel braking (ie. DSC/DTC) to control the slipping wheel to transfer torque to the other non-slipping wheel.

Yep, they sure do.
In their Sport Package option.

Yeah, can't imagine having max torque of 300 lbft only a dab of the right foot away only 700 rpm from idle. And this will be available flat as a table all the way up to 5000 rpm!

Quaife is amazing....:rocks:

I installed one in my G35, it was a HUGE benefit.
The Quaife is a Torsen style unit.
No popping/snapping/binding & noise like a clutch style.
and as far as the viscose style.... hardly worth the effort

I would definitely install a Quaife in the 335i when the time comes.

The best handling car available in the US does not have an LSD either. It is finally optional this year. The car is the lotus elise.

Anyone have the $ figures for a Quaife for an E90 yet? It will have to be solid to contend with the 335...

It should be in the same $14 - $1500 range.
No problem with the Quaife being tough enough.
They have a great rep.

Isn't the DSC like having a LSD?

It puts power to the wheel that needs it and slows the wheels that don't.

I've driven both, and I can personally say, I like the positraction with the assistants of a computer sensor slowing the inside wheel to keep the momentum of the car moving forward way better.

For every day driving that is.

From BMW's web-site.

" The system continually processes data from the anti-lock braking wheelspeed sensors. Any time a rear "drive" wheel begins to lose traction, the system modifies the engine's electronic throttle and ignition timing to reduce torque. It also can act on each rear brake individually or simultaneously, as needed, to bring wheelspin under control. Dynamic Traction Control aids driving in deep snow or sand."

The same yeah??? Maybe not???

But I like it.

You can't really compare. The elise probably doesn't need an LSD with , what, around max 130 lb-ft of torque up high around 5000 rpms from a 1.8L normally aspirated engine. I wouldn't consider that a torque monster like the 335i. I seriously doubt the elise will have much problem putting that 130 lb-ft down to the ground, despite it weighing over 1000 lbs less.

Similar intentions (to control wheel slip) but different way of achieving it.

Kinda like having a gold-plated ring vs. the real gold thing. Both look nice, but only one is truly gold.

As mentioned by previous posters, most (probably 99.99%) drivers will only need DSC in their type of driving. The LSD is really for certain drivers who appreciate it around corners, and especially for cars with higher hp and torque, the 335i for example.

Instead of being slowed down by the computer/DSC shutting down the power by applying individual braking and/or cutting the throttle back, the LSD (due purely to its mechanical design) allows the power to be laid down to the ground evenly with little slip and little lost energy.

Here, maybe this link will help to explain it better than I can:
