Helical lsd differential is suitable for Porsche with g50 gearboxes, to replace the standard open differential. A direct replacement for the standard Porsche differential. 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 thi...(choose a part on the right to read more)
