Thanks Schroeder02. Man, very tempting! I'm betting the Dunlop Direzza Sport Z1 Star Spec is a much better track tire. It rates great on tire rack, and costs the same as the KDW2. I hadn't really considered the Dunlop.
I wanted to go with the BFG, GForce or KDW, because they're manufactured here, and I had talked with a guy at work who I saw ran the KDW's on his WRX track car/ daily driver, and recommended them. Very tempting!
