Busch and Carl Edwards were the two drivers selected for a two-day Goodyear tire test at Atlanta Motor Speedway, and the chance to run at the 1.54-mile track was a coveted one since NASCAR placed heavy restrictions on testing for the 2006 season.

"I feel a bit rusty right now for a few different reasons," Busch said. "Just getting back into the car. I was a bit nervous at first. It's been fun so far."

In 2006, Nextel Cup teams are allowed to test at only Charlotte, Daytona, Las Vegas, Richmond, Homestead-Miami and Indianapolis.

Busch said he was surprised when Goodyear officials contacted Penske Racing last week about participating in tire test at AMS, but he welcomed the chance to get acclimated to the Dodge on a high-speed downforce track like Atlanta.

"It definitely feels different," Busch said. "The car turns better than what I am used to, but the rear end doesn't stick as good. I think that is where the Dodge needs to make some changes and see if we can't get the rear end to stick a little bit better, and then we can race hard on these fast tracks."

The two teams got a tremendous break with the weather, as Busch and Edwards tested in near-perfect conditions at Atlanta.

"It's a great time to test. It'll give us a good read," Busch said. "It's a matter of adjusting to balance."

Edwards, who won both races at AMS in 2005, said he was just trying to shake off the cobwebs.

"The last race we won here, the fastest line was right up by the fence, and I am not even running that right now," Edwards said. "We're just kind of doing a test. [crew chief Bob] Osborne and I just talked about kind of just knocking the rust off from not being in the racecar for a while."

The test continues Wednesday at Atlanta Motor Speedway. It is closed to the public.
