Maximize traction and performance with the Quaife ATB helical limited slip differential for the Fiesta ST MMT6 gearbox. A direct replacement for the standard open differential, the Quaife ATB differential transforms your car's performance and improves cornering.
Unlike a conventional plate-style limited slip differential, the Quaife differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and never locks harshly with a set pre-load of wheel slip across the driven axle. Instead, the Quaife differential automatically biases the torque away from the spinning wheel, across the axle to a constantly varying degree.
