On the lowered stance, the inspectors (not all of them) go by the German TUV requirement that the lowest hard part of the car has to be at least 10 centimeters from the ground. In laymans terms, grab a can of Goya beans which is 10 cm's and slide it under the car through the front and sides, with exception of the jack points, if it bumps with anything else under the car, they might give you crap.
That is of course, if you go get your car inspected by the german idiots over at Kapaun.
