GRAND-AM track action resumed today as the Alex Gurney driven #99 GAINSCO Auto Insurance Corvette DP topped the timesheets at Indianapolis Motor Speedway.

A total of 105 cars run throughout the day split between the Rolex Sports Cars Series and the Continental Tire Sports Car Challenge ahead of GRAND-AM’s Brickyard debut on 27 July.

The #99 Corvette DP ran fastest in the first and third sessions as Gurney and team-mate Jon Fogarty got to grips with the famous Indy circuit. “Obviously it was a really good day,” Gurney said.

“The times are close [throughout our sessions]; we did some good work on the setup and got through a few good changes … so far so good. It is incredibly hot so we never ran any long runs, so that is still the giant question mark and maybe Saturday we will work on that.”

Added Fogarty: “It is pretty hot but I feel good. It was fairly productive and the car is comfortable to drive. We are going to have changing track conditions Saturday and probably for the race but we seem to be in a good spot. Not chasing ourselves too much will allow us to branch out, experiment a little Saturday and hopefully make more improvements.”

Ryan Dalziel was one of the drivers getting his first taste of the 2.534-mile road circuit and will be doing everything he and co-driver Enzo Potolicchio can to add to their class victories at 12 hours of Sebring and 24 Hours of Le Mans.

“Anyone who comes up through open-wheel, it's always one of their dreams or goals to get to Indianapolis,” said Dalziel, who was seventh-fastest on the day. “I've already crossed off two big ones in one year, at Sebring and Le Mans.”
