It looks like H&R wants to lower the suspension on every single car model, and this time they worked with the Porsche Panamera V6 4WD version which now sits 35 millimeters closer to the ground.
Besides developing this new spring set that enables slightly sharper handling on the H&R Porsche Panamera V6 4WD, the company will also offer an electronic lowering system (ETS) design especially for cars with air suspension.
The H&R TRAK+ wheel spacers are also part of they future plans for the H&R Porsche Panamera V6 4WD, so no more gaps between the wheel arch and the edge of the wing. 
H&R press release :
Porsche once more sets the standard for superclass automobiles with their Panamera – also when it comes to suspension. A challenge which the engineers at H&R willingly attended to work on. The result of the complex development is a spring set that brings the four-door and four wheel drive V6 vehicle with conventional suspension around 35 millimetres closer to the ground. The basic characteristics of the elegant and classic design are accentuated with this dynamic package – without weakening the overall concept of this luxury car. With the H&R spring kit the handling could also be made a shade more dynamic – needless to say that the comfort of this top class sportscar is not reduced.
An ETS (electronic lowering system) for the air-suspension cars will soon be available, too.
A further highlight can be obtained from the H&R TRAK+  Wheel Spacers made of high tensile aluminium. The small gap between the wheel arch and the edge of the wing can thus be visually perfected, which results in an even more powerful appearance.
The full range of H&R products for more than 1,350 vehicle types is available at all good specialized dealers and along with the expected H&R quality naturally always come with a general operating permission (ABE) or TÜV certificate of conformity  (Teilegutachten).
