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.

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.

The B1 Dynamics Package is a combination of three Birds-exclusive performance upgrades designed to transform the chassis of the BMW 1 Series.

The quaife if amazing. Allow for much more of the available power to be put down coming out of bends, or controllable tail out action if one desires. Best mod money one can spend. BMW really should have spec'd this car with an lsd from the factory.

Just so you know I am not concerned with the deposit, just want you to get the diff back so you can make another m135 owner as happy as I am with the quaife.

Thanks, Chris
