Hi Matt,
Thank you for contacting!
Feedback on the Quaife differential... unreal piece of kit! Transformed the car in such a positive manor, wasted too much time not having one on my car, feels a lot safer too! Two thumbs up from myself
Thank you for the sale of the differential! Best piece of kit I've ever had fitted to a car I've owned

Hi Kevin,
I tested the car last couple of days and I am highly impressed with everything. The power, is amazing and more importantly it feels really safe to use. The traction is phenomenal. When out on a test drive yesterday, I had no choice but to drive over a pot hole in the road and it seemed to gobble it up! Whereas before in a similar car it would crash in and out of similar holes in the road if unavoidable.

NEW BMW Quaife ATB Limited-Slip Differential - G20 & G21 330i, 330ix, 320i, 320d
The popular QUAIFE Automatic Torque-Biasing LSD is now available and in stock for many of the new BMW G20 3 series models, exclusively at Birds.
Once installed, drivers will notice an immediate difference as the Quaife ATB automatically biases torque across the axle to the wheel with most grip. Unwanted wheel-slip is greatly reduced, enabling drivers to exploit the full potential of their BMW for the first time.
