On the last track mentioned above with my 3.2 A3 with S-Line suspension. This was my first longer ride over 150 km at a time. This constant extremely hard hopping was really annoying. At the corner around Karlsruhe up to the Hockenheimring it was particularly violent. I felt like at the waistband, when my comrade built out the shock absorbers in his yellow Ascona and you always hit the roof sky on bumpy roads. In short: It is on a long distance n too hard and an electronic regulation of the degree of hardness would be very useful from Audi. I would order this immediately with the new purchase. Just so much greeting from Munich
