Quaife ATB Differential

The Quaife Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster. How? Simply by getting the power to the ground!

The Quaife differential powers both drive wheels under nearly all conditions, instead of just one. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

When accelerating out of a corner, the QUAIFE biases greater power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.
