High-Bias Torsen Differential

Tuning the center differential provides one of the most significant performance gains available to the Quattro owner. The standard torsen center differential in the A4 provides a 2:1 torque distribution capability. This enables the end of the car with traction to deliver twice the torque being delivered by the end of the vehicle with the least traction. The STaSIS High-Bias Torsen raises bias from 2:1 to 4:1, allowing up to 80% of the engines power to the front or rear wheels.
