Set depth (center hub to fender center): ~ 32cm front and rear ~ 33,4cm
Effective Lowering in my case: front 60mm, rear 55mm
Used tires / wheels 205/55 / R16 on Road America (original VW)
Practicality: Borderline, but still mobile. Hardly ground clearance (see photo of the red Passat), so always watch where you breaks forth
Cost TÜV registration: Since I had nothing else changed, it only cost 40 euros
Ride: suspension acts fairly soft (within the meaning of comfortable) compared to my FK High Sport Astra GCAB.
Therefore: If you like it harder, had better choose another chassis (eg KW with adjustable firmness)
Now I just have to make to adjust your headlights on occasion, as it was forgotten.
Note: For xenon there should be problems when you go too deep down! (= Reconstruction measures required)
