Dear Kevin,

At last, I have my laptop back so, as promised, I thought that I should put pen to paper, or fingers to keyboard, in this case.

The popular QUAIFE ATB Limited-Slip Differential is now available and in stock for the F20 M140i, F22 M240i, F30 340i and F32 440i, exclusively at BIRDS.

The Quaife ATB Differential provides significantly improved traction and handling for powerful rear-wheel drive cars, and is an absolute must-have performance upgrade for owners of these brilliant driving machines.

Hello gents,

Having been made aware of some interest in a group buy (and increasing pressure from a few of the members...!) we'd like to promote a special offer on all Mercedes Quaife ATB Differentials.

Rather than a group buy, which can be a bit difficult to manage from outside the forums, this is a limited-time special offer for MB Club members only for the month of February 2017.

Transform how your Z4 applies power to the road with the popular Quaife ATB limited-slip differential at a special offer price, down from £1530 to £1320 installede.

Hi James

After more than 10000 km and a trackday with the Qaife LSD and the suspension I do not regret the Money spent.

The setup improves the ride a lot without being soft. Even though the car sits lower than the original M-suspension

It handles full load without problems.

On the track with Conti  sportcontact 5 (NON rF) it handles very well and balanced.

The LSD is smooth and provides lots of grip.

The setup is full value for money .

Best regards

Carsten
