Has anyone used A6's on the track rather than autocross? Hoosier advised they would be fine for 25-30 min sessions but I was wondering if anyone had any exereince with them? Info on the best way to do the initial heat cycle would be very helpful. Hoosier recommends scuffing the A6's in for autocross use but didn't have any recomendations on what to do when using them on a road course.
