"The track too tough to tame" gets the spotlight once again this weekend when NASCAR invades Darlington Raceway for the Dodge Challenger 500

Kyle Busch heads into Darlington after registering another Top 5 finish at Richmond last weekend, where he placed second in the Dan Lowry 400. Busch now leads the driver standings by 18 points over Jeff Burton, but he isn't the favorite at Darlington this weekend.

The favorite, at least in the oddsmakers' eyes, is Carl Edwards at 4/1. Edwards leads the Sprint Cup Series with three wins on the season, but he's never crossed the line first at Darlington.

Edwards' best career finish at Darlington was fifth place in this race last season, but with one of the fastest cars on the circuit this season Edwards could be hard to catch if he can get out front on Saturday night.

Right behind Edwards on the odds list at is Busch at 5/1. Busch recorded his sixth Top-5 finish of the season in 10 races last week, but he'll be looking for his first career win at Darlington this weekend. In three career starts at Darlington Busch's best result was seventh place two years ago.

If you're looking for multiple race winners at Darlington this week your best bets are likely Jeff Gordon, Jimmie Johnson, and Greg Biffle. Gordon, a 12/1 underdog this week, won at Darlington last year and has seven career victories on the track.

Johnson and Biffle each have a pair of wins at Darlington, with Johnson winning twice in 2004 when Darlington had two races, while Biffle won back-to-back in 2005 and 2006.  On the odds list this weekend Johnson is at 7/1, and Biffle is a 12/1 underdog.
