Quaife ATB Limited Slip Differential for Automatic 135i
Quaife, The Ultimate Differential is now available for your 335i at HP Autosport, 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: Top tuners using our Quaife LSD: Berk Technolgy's Redline Time Attack 135i Burger Motorsport world's quickest 135i Vishnu Tuning Most of the automatic transmission 135i come with a bolted diff, so all you need is the Quaife and a local shop capable of the install.

I have the Nismo mechanical LSD on my Z and frankly it affected the daily-drivability. It's too agressive and clunks like hell!
How is the Quaife compared to that? will it feel like OEM LSD?

You can always purchase a complete housing with a quaife installed, while your there why not change your ratio to 3.46 for greater acceleration. Ask Harold for details. I have done a few now and it is fantastic with a ratio changes

Quaife for your automatic 135i is good in stock.
Complete Quaife FD for your manual 135i is ready to go as well! |

Any idea if the Quaife will work in a 128i? Since it is a manual, I assume it has the same welded gear problem.

I've had a Quaife on my 130i before, good product. Now I have a 135i, and considering upgrading this one also. On thing that I'm wondering about is the stock "LSD-function" on the 135i/335i that works through the brakes, (that functions even when you have the DSC/DTC completely turned off.)
- How does the Quaife unit work together with this function and is there a way to turn it off? |
