Quaife Replacement LSD – BMW
When the question is asked ‘what is the first modification you would recommend doing to my car?’ there can be only one answer – the Quaife Replacement LSD.
As a direct replacement for the standard, factory ‘open’ differential, QUAIFE’s ATB Helical LSD unit can transform the performance of your car. Unlike a conventional plate-style limited slip unit, QUAIFE’s ATB Helical LSD unit relies on gears, rather than clutch plates for its operation.
That means it is much smoother in operation, because unlike a conventional plate-style LSD, it never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree and never locks.
To the driver the results are significant performance improvements;- superior, controllable traction without the harsh steering wheel snatch or torque steer that have long been associated with performance differentials. These traction benefits can also be utilised in rear wheel drive vehicles, while QUAIFE ATB Helical LSD units offer significant traction advantages fitted to the front of four wheel drive cars.
