Mountune Quaife Torque Biasing Differential 2016 Focus RS

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.

Benefits over a standard open differential:

• Improves turn-in (helps with drift mode!)
• Maximise traction
• Minimise wheel spin
• A maintenance-free design which retains the standard oil lubrication
