Complete 2.56 HPA Quaife Final Drive for your 135i N55 DCT

Quaife, The Ultimate Differential is now available pre-installed in a 2.56 brand new BMW final drive housing for your 135i N55 DCT at HP Autowerks, Inc.

"The Quaife Automatic Torque Biasing Helical LSD Differential enables a car to accelerate more rapidly and corner faster. How?

Simply by getting the power to the ground.

With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.

The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In cornering, while accelerating out of a turn, the unit biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife differential also controls loss of traction when the drive wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife ATB Helical LSD differential's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage, whether on the track or on the street.

The Quaife differential is extremely strong and durable, and since it is gear-operated, it has no plates or clutches that can wear out and need costly and regular replacement. There is no maintenance required to the unit, so you can fit and forget.

The Quaife differential is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the cars towards its limits.

The Quaife differential is proven in everything from SCCA Rallying to drag racing and Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.

Expand your vehicle's limits with the Quaife ATB Helical LSD Differential!"

Here is a video on LSD:

The complete Quaife final drive unit is. All new parts, including the machine work and set-up. Remember the added cost is from the brand new BMW final drive, which is around $1800.

is there any special installation requirements to install the Quaife with a bolted ring gear, besides the normal R&P setup and adjustments, such as machining? I'm almost set to order Quaife the but I want to make sure I understand all the cost first ($1,305 + install).

No, nothing special on the bolted ring gear final drives - you will only see that on the autos now.

Once in a while you will need to grind a relieve to get the ring gear/Quiafe into the final drive housing. You will see what I mean when you get to that stage, but it's very minor work.

^^ so its 1k before shipping and after the core fee for the entire unit, or just the lsd?
Available for the 6 spd?
Am I right in assuming this will look stock, so bmw wil have no way to tell you have a aftermarket rear diff. ?

Yes, the manuals have a core charge of $1k instead of the $1800.

There is no way to tell by looking at it.

Very interested... need to know more about quaife vs wavetrac or os-giken (clutch type diff) etc.

I HATE the fact that my "ultimate driving machine" is a one tire wonder.

Thanks

Wavetrac has no such application at this time. OS Giken is mostly not as well.

Quaife and a custom Salisbury(3 disc clutch type) can be built for the 135/335i DCT.
