I have on my audi the nuvolori wheels, been on my car for about a month, however i have ordered the Rs6 alloys, as i feel these wheels dont suit the car very well.. which will go on this sat, is this the right choice? i also plan to lower the audi, wots the best way to go about this? springs? Shock kits? and by how much without rubbing and with people in the back? Any help would be great!!
