Lets start this off by taking a look at the rear of the field, as this really sums up what US racing was all about during this period. While at the front end of the grid are a squadron of Porsche 935s and BMW 320 turbos, run by well equipped professional racing teams, down the back are the weekend warriors in their older Trans-Am Camaro's, B Production Corvette's, and the like. But its these guys that make these events so interesting, and keep many of these older cars running as the rules move away from them. Note the C2 Corvette on right of picture. By this stage nearly 15 years old, but still being put through its paces.
