I had these installed two weeks ago. I am very pleased with them. The ride is much quieter than the KDWs were, at least with only 1,500 miles on them. They may get louder with time but they are not directional tires, so they can be rotated from one side of the car to the other to even out wear and keep noise down. They perfomance is impressive, the limits are really too high to approach on the street. I use them for autocross and breakaway is very smooth and predictable...the car even lifts the inside rear tire 5"-6" off the ground now (with Koni adjustables and an Aussibar). Wet traction is very good unless there's standing water, then they get a little skethcy, but not enough to be scary. Wear has been reasonable as little has shown after 1,500 miles including one autocross. The only think I dislike is that the are firm, but not quite as stiff as I like, requiring just over 40psi to prevent rolling over onto the sidewalls in autocross. The tires look great on the car if that matters. I am very impressed with these tires and will buy them again.
