How is the Quaife ATB Differential superior?

The BMW M Differential uses a basic clutch type LSD which wears out over time, deteriorating in performance before eventually needing to be replaced. They are given an average lifespan of around 60,000 miles, but we have seen them fail as low as 30,000 miles when used aggressively. What's worse is a new BMW M Differential for the E46 M3 will cost you more than £3120 + fitting... 

When the time comes to replace your BMW M Differential, the QUAIFE ATB Differential is a superior solution. By using a clever scroll gear system that biases torque to the wheel with more grip, it has no wearing components and comes with a limited lifetime warranty. Its torque-biasing design is better at putting traction down too - constantly detecting wheel slip and manipulating the torque accordingly, and applying it in a progressive, user-friendly manner.
