Hello James,
 
I have to say that the cars driving behaviour with the LSD changed
dramatically! It is almost incredible how much grip I have at the end of the
bend on dry streets and on wet asphalt the car is a real drift machine. It´s
awesome and worth every Cent! Thanks again. 
 
Regards, Viktor

Hi James,
 
The core will be shipped out tomorrow! I just wanna say it's the best mod ever!!!! I have Hartge Ecu and a full turbo back exhaust, and it used to lose transaction all the time. Now, first gear, second gear, WOT no problem at all!! It still slips a little sometime, but nothing like it used to be, totally transformed the car! I'm very very happy!!!
 
Thanks
Derek

Hello Kevin,
 
Everything came in perfectly, it's on a car now, and WOW, wasn't really expecting that much. It's just superb, exactly what i wanted and perfectly suitable for our roads. Now it is a car, which completly mirrors my wishes and needs. So once again, really thanks for your hard work and this excellent piece of kit. 
 
Regards, Tomas

Testimonial - F30 335i - Quaife LSD - Mr Zanchi

I got the car last Thursday, and I had the chance to drive it straight away on a particular highway (Serravalle-Genova), which is very very good for testing a car setup. Plenty of curves that you can do at around 120/140 kmh max (very narrow curves), so I had a chance straight away to test both the new suspensions and the Quaife. It was perfectly dry.
 

Quaife ATB Mercedes Limited Slip Differential Conversions

The Quaife ATB Differential provides significantly improved traction and handling for any powerful rear-wheel drive car, and is a must-have upgrade for Mercedes owners looking to maximise the potential of their machines.

Once installed, drivers will notice an immediate difference as the Quaife's patented ATB design automatically biases torque across the axle to the wheel with most grip. Unwanted wheel-spin is greatly reduced, enabling drivers to exploit the potential of their machines for the first time, leading to a more exciting, rewarding and rapid driving experience.

BMW F30 335i, 328i, 330d, 335d QUAIFE Limited Slip Differentials

The Quaife ATB limited slip differential (LSD) is now available and in stock exclusively at Birds for all F30 3 series and F32 4 series variants.

The Quaife LSD is a unique device that mechanically senses traction loss and distributes torque to the wheel with most grip accordingly. The result is a transformation of the car’s overall performance - increasing acceleration speeds, cornering speeds, and improving the general handling, grip, and dynamics of the car.
