Kansas City, Kan. • Jimmie Johnson didn't qualify where he wanted, and his car never quite cooperated during the final practice session at Kansas Speedway. So he spent Saturday evening in the garage area, going over different setups with the rest of his team.

That dedication, that attention to detail, is a big reason he's chasing his sixth straight Cup title.

Johnson and his team must have figured things out. The defending series champion stormed to the front early Sunday, then weathered a series of late cautions before holding off Kasey Kahne in a green-white-checkered finish for his first win since April.

"Jimmie was very dedicated last night with us, trying to figure out the setup of the car," crew chief Chad Knaus said. "We pored over a lot of combinations, and we came up with a good one."

Talk about an understatement.

Johnson led 197 laps in one of the most dominant performances the track has ever seen. The victory was the 55th for Johnson, moving him into a tie with Rusty Wallace for eighth on the career list, and the 199th for team owner Rick Hendrick.

"The competitor in all of us, we've known we've been close," Johnson said.

Johnson stumbled through the first two races in NASCAR's version of a postseason, and was 10th in the standings heading to Dover. A second-place finish last weekend gave him confidence, and his first win since Talladega moved him into third in the Chase behind Carl Edwards and Kevin Harvick.

"I know what my team is capable of," Johnson said, "and we showed today what we're capable of when we're all performing at the top of our game." —
