Hello all, I have 10mm distance discs on my SL55 rear. Actually, this looks quite good, but 15 mm would be optically ideal. Has someone installed 15mm windows in the rear? Has someone installed distance discs in the front? my Mercedes-master advised me for the front of it, otherwise one swims constantly in the lanes. Is this true?? I am not only about the optics, it should also be easily mobile. Maybe someone can help me further. VG von Ulrich
