For starters I drove the AVS DB's and they were indeed really quiet, but they were really soft and for lack of a better term "touring-tire feeling". On the autocross course they did not handle well, but if you are a softer non agressive driver looking for less performance and more comfort they would be good, but if you are looking for AVS sport-like performance...look elsewhere. As for the RK, that fittment will come right to the edge of the wheel well and not stick out at all. In the 17x8 fittment it weighs exactly 17.5 lbs each.
