There is little doubt that whilst BMW have endowed this car with superb dynamics, there remain significant margins where performance can be improved. We have co-ordinated all of the necessary equipment and expertise to transform the braking, handling, traction and ride quality, so that the driver is able to fully communicate with the chassis, and truly elevating the dynamics to provide the real ultimate driving experience.

Design:

Perhaps the innovative design of the Quaife ATB differential is what has attracted so many BMW enthusiasts around the world. Unlike regular limited-slip diffs that use wearing clutches (eg. the ones used in BMW M power cars), the Quaife is gear operated and will never wear out. The design enables a smooth, progressive transfer of torque between the rear wheels with no fuss, and applies power to the tarmac with maximum effect. The result is a transformation of performance. In 20 years of tuning BMWs this has to be the most effective tuning element we've ever had to offer, which is why it is the first enhancement we advise to all BMW owners looking to increase performance. Backed by a limited lifetime warranty.


DTC interference:

In a recent survey to BMW customers who have bought a Quaife differential, we asked what their main reason was for the purchase. To enhance performance was at number 1, which is understandable. But at number 2, the reason was to eradicate that irritating, flashing yellow light. Dynamic traction control (DTC) or 'electronic braking' has limited the new BMWs to quite an extent, which most of you will know. When you put a Quaife limited-slip diff in the car, it almost removes that light completely whilst working in perfect harmony with the BMW's electronic systems. We guess that BMW had prepared them for a limited-slip diff option, but decided to have them as a unique element in the M power BMWs. The Quaife is the ultimate solution, no question.

Performance:

A single tuning element that increases acceleration, cornering speeds, traction, steering and handling to such a degree that customers say it 'completely transforms the car'. This is why we rate it so highly and have invested so much time and money into our Quaife BMW worldwide project. The majority of people are too interested in getting maximum power gains from their engine, not knowing that the BMW's electronics will restrict them. We can offer combinations of a Quaife LSD and engine re-map/anti-rollbars/suspension kits and more, dependant on your preference and what we would advise for your specific BMW. Our experience and expertise have enabled us to create some M Power-matching BMWs over the years, and now we have a new trick up our sleeve in the Quaife limited-slip diff...

We have applications for the 90% of the BMW's, including the 325/328/330i.

[Me_Hi]

I found out how much for a 328 ( I assume 325 as well ) low $12**.00 with stub axle seals and free shipp to continental US.

Next year my baby will get it...

Do I really feel like spending that much. I don't thing so. i should just do the 3Stage manifold conversion instead.

Hey ME_Hi -By the way were did you get your hood, that looks sick.

Three Stage is very expensive. Parts and a tune will run you ~$1500.

No, gear ratio change is not part of the Quaife install.

If you have a manual, you can step up to 3.46 from 3.08. As for auto 3.46 is perfect for it. I can PM you prices if you are still interested.

Harold@HP

LSD is a big difference, it's a great performance mod.
for the price of a full exhaust or even the PE for the NA why
not this LSD.
You will feel this mod performance for sure.
