This helical lsd differential is a direct replacement for the standard Porsche open differentials. suitable for Porsche 987 Boxster s and Cayman s models. automatic torque biasing differential enables your car to accelerate quicker and corner faster.

The differential powers both drive wheels under nearly all conditions. With an ordinary open differential (standard on most cars), precious power is wasted during wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip, along the path of least resistance. The differential, however, does just the opposite. It senses which wheel has better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

Not for tiptronic model!
