....I've run the DW's on my wife's Fusion, hardly a sports sedan, but I was very impressed.
A car buddy I trust runs the DW's on all of his cars, an E39 M5, an old M635Csi, and a Volvo wagon, he loves them.
I had the previous generation Michelin Pilot Sport AS/3's and I wasn't that impressed with them.
I have Bridgestone S-04's on my 2004 Boxster S and I'm really loving them. For the money, they are hard to beat, and you can find them in stock at any local Firestone store.
