please make a video of your car in snow action and dry pavement. Only have seen the video of Terry Burger launching with his quaife at the track and it was a rocket!

The Differential is the last piece of machinery which hands the power from the engine to the wheels. In our car's case, this is the rear wheels. Upgrading to a Limited Slip Differential changes the way in which the car is allowed (or capable) to transfer power between both wheels when they are not rotating at the same speed.

When one wheel is slipping in a standard diff car, power is removed from the wheel with traction and handed to the one without. In most scenarios DSC will also apply brakes at the same time to the wheel with traction to slow it down in an attempt to correct the slippage (otherwise known as 1 wheel moving faster than the other)

On a car with an LSD, power can be given to both wheels unevenly, this allows for much more effective drifting and car control, as well as maintained forward motion during instances of slippage. When you are on a track, wheels slip all the time... this is why an M car can often out shine a non-m because when it starts to slide, it can keep moving forward... thus being faster around the track (in some cases)

If this wasn't entirely accurate, someone can correct.

If you have the e-diff (which I agree works quite effectively in most circumstances), why would you add a Qaife? Is this for track work or some other heavy duty application? I'm just curious to what you are going after here and the perceived advantage. Thanks!!!
