Hi guys, no doubt some-one must have asked b4 but im new to the audi scene (coming from Japworld) but will genuine 19" RS4 alloys fit my a4 b7? My car already has the rs style wheels but in a 18" size. The set im looking to buy has 255/35/19 tyres, Wouldnt this be to wide? I was thinking more like 235/35/19 as ther only 8.5j. Also Would i need spacers? thanks guys.
