Panamera models with optional air suspension utilize four sensors to control the ride height. This is accomplished via the use of a small linkage or link which connects the sensor to the suspension. As the car is raised or lowered, the link moves the sensor up or down sending a signal to the computer telling it how high the car is. When you replace the non-adjustable factory link with this adjustable design, the output of the sensor makes the computer believe that the car is higher than it is. So, the computer will lower the ride height. The simplicity of this setup is that it retains full functionality of the factory system. Be warned, all adjustable lowering links are not the same! These links are machined al...(choose a part on the right to read more)
