Risi Competizione has revealed that Jaime Melo and Mika Salo will run without the assistance of a third driver in the Petit Le Mans this weekend at Road Atlanta.

The duo, who won at Mosport and go into the weekend as the defending GT2 drivers champions, but have decided to run the race alone because of the risks involved in bringing someone else in to join them in the #62 Ferrari 430.

"We did it just the two of us last year, after Johnny [Mowlem] hurt his wrist in warm-up," Salo said. "It's going to be a hard race for sure and, depending on the weather, could be a very hard race, but Jaime and I know each other so well and the car so it's risky to have another driver. We trust one another 100 per cent. There will be long stints and it will be tiring for both of us but we can do it of course.

"It's a nice track, I like it, but it will be really difficult with the prototypes as they run at such a high speed. There will also be lots of drivers in the prototypes who don't' know what they are doing - ones that aren't as experienced in the American Le Mans Series as others."

Krohn Racing will resume its links with Risi for the final two races of the year, with the green #61 Ferrari being piloted by Eric van de Poele, Tracy Krohn and Nic Jonsson - with the trio confident of a strong result on their return to the series.

"We're getting ready for Petit again this year," Krohn said. "We had a very good result at Sebring, although not so good at Le Mans. Nic and Eric are very familiar with the track, as am I, which makes a pretty good combination. With also having our Krohn Racing team right at Road Atlanta, we've got a lot of laps around that track and the Ferrari is a wonderful car to drive. I really enjoy driving it."
