Birds are the exclusive worldwide distributor for BMW and Mercedes Quaife ATB Differentials.
Birds B-Series Suspensions include specially valved Bilstein shock absorbers and accompanying bespoke Eibach springs, designed to improve ride and handling on U.K roads.
The Quaife ATB Limited-Slip Differential provides significantly improved traction and handling for powerful BMWs and Mercedes.
Once installed, drivers will notice an immediate difference as the Quaife 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 machines for the first time, leading to a more exciting, rewarding and rapid driving experience.
