Quaife Differential for Z4 3.0

HP Autosport · 11-17-2008, 04:42 PM

Quaife, The Ultimate Differential is now in stock for your Z4 3.0 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!"

According to the Quaife website, the only authorized fitting center in the US is Taylor Engineering in TX. If the Quaife LSD is installed by someone other then Taylor is the warranty voided?

And we are the US BMW Quaife stocking dealer and installer authorized by a Quaife Specialist BMW Distributor.

Taylor Engineerings handles the motorsport division only, but you may want to ask if they will install your Z4 Quaife if you are in the area. If not, we can certainly recommend an installer nearest to you.

Your warranty will not be voided if the Quaife is installed and used according to the warranty guidelines.
