We are excited to announce that we can now supply Birds' new Quaife ATB differential, designed specifically for BMW models including the E46 M3, E90/92 M3, E60 M5, E63 M6, E85/E86 Z4 M, and E82 1M.
The Quaife ATB differential QDF27N is engineered to be compatible with the original differential output shaft flanges, saving customers money on conversion costs.
Why Choose the Quaife ATB Differential?
BMW's factory M Differential uses a basic clutch-type limited-slip system that degrades over time and needs replacement, typically around 60,000 miles, but aggressive driving can reduce this lifespan to as little as 30,000 miles. Worse still, a new BMW M Differential for the E46 M3 costs more than £3120, excluding installation.
When it’s time to replace your BMW M Differential, the Quaife ATB differential offers a superior alternative. With its innovative scroll gear system that directs torque to the wheel with more grip, it has no wear-prone components and comes with a limited lifetime warranty. This torque-biasing design enhances traction, constantly adjusting torque to manage wheel slip in a smooth, user-friendly way.
