Salt Lake-based Miller Racing will compete in the Grand-Am Continental Tire Sports Car Challenge Series on Friday at the Indianapolis Motor Speedway. Miller Racing's Ford Mustang Boss 302R will again be co-driven by team principal Roger Miller and Ian James. The race at Indianapolis will take place on a 2.5-mile, 13-turn course that was used by the Formula 1 World Championship from 2000-2007. The NASCAR Sprint Cup and Nationwide Series will both be racing at Indianapolis this weekend. As a result, the Grand-Am Rolex Series and the Continental Tire Sports Car Challenge will have its schedule compressed into one day. It starts with practice at 8 a.m., followed by qualifying at 9:15 a.m. The 2.5-hour race starts at 1 p.m. Fortunately, Miller Racing was able to join other teams from the series in a two-day test earlier this month, which helped the drivers and crew get familiar with the circuit. Traffic, however, could be an issue. The entry list for the race shows 75 cars, including 36 in the Grand Sport Class and 39 in the Street Tuner Class. Miller Racing competes in the Grand Sport Class. "I'm excited to be able to participate in this historic race at the Indianapolis Motor Speedway," said Miller. "Once again, I'm cautiously optimistic about the outcome of this race. I feel that we found a good set-up when we came here to test earlier this month and the team is as good as ever. With a little luck and our best effort, we should do well."
