GAINCSO duo Alex Gurney and Jon Fogarty are chasing more grip following first practice for the latest round of the Grand-Am Rolex Sports Car Series, even if the duo still emerged third quickest at Barber Motorsports Park.

Although the Pontiac Riley was well on the pace, half a second nonetheless separated them from the leading No.75 car of Colin Braun, a gap both Gurney and Fogarty are eager to break down as the weekend progresses.

"The GAINSCO team had a good first day, and we got through a lot of changes," Gurney said. "The 75 car looks like the clear leader right now, so we have some homework to do. Luckily, it's a long weekend and there's plenty of time to get the car sorted.

"We've got to work on balance - if there's a little problem in every corner, it'll all add up. Both Jon and I were fighting understeer quite a bit, so we'll go to work on that and I think we'll be right there come Sunday."

Nonetheless, the car got through the day without any major problems and save for trying to catch up with their leading rivals, it was a test they could otherwise be satisfied with.

"The car's not right where we want I," Fogarty admitted. "There's quite a gap to the 75, but I think we're capable of closing that. Luckily, there was nothing that made us scratch our heads - we know what we need to do to get the speed, but it's the path we take to get there that's the question.

"This one time we're fortunate to have some extra time in the weekend, so we'll use it to our advantage. The weather is taking its toll too - the heat is brutal in the car right now."
