I have read mixed reviews about the Quaife LSD. A lot people say its awesome on dry pavement and they feel that the car has more control. On the other hand a few people say that in rain they feel like the car is hydroplaning and it slides out way easier. What's the deal? Anyone with the LSD have these issues?

BTW any loss of MPG with the install of the LSD?

Not unsafe but takes getting used to....you have more control over the car, it will be more predictable..... With the open diff, around a corner, wet or dry, it might slide, it might just spin a wheel..... With the LSD, it will always slide,if you want it to....

I think it's safer, cause it's consistent

Slides with Traction control on or off? Im thinking that the car cant make any or very little lateral movement with DTC\DSC on.

Try this.

Exactly my take. In particular if you have a tune - but also with stock power you'll be able to let the rear slide out if you want to, in particular in wet conditions.

Several weeks ago I had a malfunction of all traction assist systems and gave a bit too much throttle when going around a corner in the rain. The rear came out very quickly but it was easy to countersteer it (at least if you know how to do that). Without the Quaife it would have been much more dangerous and difficult to handle, as the open diff leads to unpredictable reactions of the car.

My advice: If you want to drive like that, i.e. using the whole capability of the car, go to some driving instruction classes. I did that, it's very helpful.

I don't know if this applies to Quaife LSDs, but all the cars with LSD that I've owned were twitchy and less than 100% stable at highway speeds on snow. OTOH they were super fun on wet freeway ramps.

A better question (instead of "Quaife LSD unsafe in certain weather?") - "My driving skills - unsafe in certain weather?"
With Quaife your car is more predictable and controlable in rain, but you have to know how to control it.

Is there one available for AT?

Yes, transmission type doesn't matter with respect to the differential.

Have you guys considered factors such as:
1) tires (summer vs all season)
2) tire wear (many of my real life friends are guilty running tires 4/32 or less in the rear)
3) car rountinely aligned (camber/toe, etc.)
???

Also, I have a general question: is the Quaife a 1.5 way or 2 way or other differential?

Great video. That looked awesome. I am not spending another penny on my E90 until I buy a Quaife.

That is only partially true as there are a number of different versions, and the one you need to choose does depend on whether you have a manual or automatic transmission (gear ratio etc.).

To be frank, if you are pushing a car hard enogh to let the rear slide out, the differential isn't creating the danger. You're driving style is. At the limit, a mechanical LSD is actually safer IMO. Knowledge of proper car control is essential. No traction control system or LSD can defeat the laws of physics.

Agree with everything posted above. LSD puts you even closer to full control of the car...how great your control is is up to you.

I agree. Anyone who gets an LSD and doesn't play around with their car in a wet parking lot to determine the changed characteristics of their car under hard cornering; is asking for trouble. You've got to learn how your car handles before you start turning off your traction control in spirited driving situations.

Interesting....I wonder why these people keep saying that they feel like their car is hydroplaning.. I guess i'll need to go to a shop and see what they have to say. I have had cars with LSD before and I know how it feels.

No hydroplaning here
Definetelly more control regardless of weather
MPG, oh well, i can still get 36MPG if i drive like grandma

P.S. F'ing loving it

Quaife -- according to his signature.

[fruition3000]

thx..BTW anyone run into any issues with the dealer in regards to warranty with either LSD installed? I don't really want to get the Dinan branded quaife just for the warranty

In doing my own homework, I have not noticed people complaining about this issue. It will not be possible for the dealer to know that you swapped the diff unless they uninstall the Quaife diff.

My $tealership refused to do some AT work under warranty due to the 'extra stress' the LSD put on the drive train.

As it turns out it was not an AT issue but still you need to pay to play at times.
