Welcome to Detroit, where the story so far this weekend is "The Taming of the Slippery Track Surface" for both the IndyCar and IMSA Weathertech Sportscar series. Every track session is luckily adding a little more rubber to the track, with hopes there might be enough to lessen the slips and slides that have plagued every practice and qualifying session thus far and provide a little forgiveness on the very technical street circuit with an already aggressive surface.
