In his wind shadow I could make up a few meters, but then I did not come by (not enough space, and I didn’t want to brake it either). I just somehow had the feeling that the nevertheless very strong with the larger air resistance At Porsche.de, however, the one with a “normally” clipped TT is really stated as unbeatable (and DOCH who wanted to). Does anyone know?
