|Select this option if the car has any of the following: The car has a modified brake pressure balancing system. The car has any kind of non-stock adjustable kinematic system or non-stock adjustable pressure valve installed in the brake system. |
NOTE : An adjustable kinematic system is a force dividing mechanism that allows different force values to be applied to the two hydraulic systems supplying the front and rear brakes.
NOTE : Many Porsches are equipped with brake balance devices by way of fixed value proportioning valves. Select this option if the factory style proportioning valve has been modified, removed, or a valve of different or adjustable value has been installed in any location in the system.
