In 1997 the configuration of the track was changed from oval to quad-oval. The project made the track one of the fastest on the NASCAR circuit. ..Exiting turn 4 is the trickiest part of the track. Steering wheel turned hard to left on exit and you straighten wheel and immediately you have to turn the wheel left again. then back to center. Then back left again for turn 1. ..Of course you have a bump in the track at exit of turn 4. Kinda gives the car a bounce.
