OSKALOOSA, Iowa — As the cars and stars of the O’Reilly Auto Parts United States Modified Touring Series continue to blaze a trail throughout America’s heartland this summer, fans and drivers alike can expect some added heat and some additional bright stars to light up the nights.

NASCAR stars Clint Bowyer, Ken Schrader and Kenny Wallace will appear at the Southern Iowa Speedway on Wednesday, Aug. 1. All three drivers will be signing autographs for the fans prior to strapping into their own high-powered O’Reilly USMTS Modifieds to take on the best the division has to offer.

While they are best known for circling America’s superspeedways with the NASCAR Nextel Cup Series, all three are accomplished short track racers that cut their teeth on the dirt ovals of the Midwest. They won't be looking for show up points, they'll be looking to make an appearance — in victory lane.

CLINT BOWYER: Bowyer, who turned 28 on May 30, currently pilots the #07 Jack Daniel’s Chevrolet Monte Carlo in the NASCAR Nextel Cup Series and the #2 BB&T Chevrolet Monte Carlo in the NASCAR Busch Series, both for Richard Childress Racing, as well as the #2 Chevrolet Silverado for Kevin Harvick Incorporated in the NASCAR Craftsman Truck Series. Bowyer captured more than 200 wins and numerous championships during his dirt track racing career. In 1996, he began racing street stocks at Thunderhill Speedway in Mayetta, Kan., and won the Modified championship there in 2000. He racked up 18 wins and 32 top-five finishes on his way to capturing the 2001 Modified track championships at Lakeside Speedway in Kansas City, Kan., and Heartland Park Topeka.

KEN SCHRADER: It was on the dirt tracks of the Midwest where Schrader’s career began. He started out driving mostly open-wheel cars and won in every division he raced, including two USAC championships. Schrader is a veteran second-generation racer, and currently drives the #21 Motorcraft/Little Debbie Ford Fusion for Wood Brothers/JTG Racing in the NASCAR Nextel Cup Series. He appears as a television analyst on Inside Nextel Cup on the SPEED Channel, and is also the owner of Ken Schrader Racing, which fields entries for himself in the NASCAR Craftsman Truck Series and the Whelen All-American Series for Chris Bristol. Schrader is also the owner of I-55 Raceway in Pevely, Mo.

KENNY WALLACE: Wallace currently drives the #78 Furniture Row Racing Chevrolet in the NASCAR Nextel Cup Series. He also works as an on-air personality for SPEED Channel on shows such as NASCAR RaceDay and NASCAR Victory Lane. He was also featured on the show NASCAR Drivers: 360 on FX. He has two brothers who are also current or former NASCAR drivers: Rusty Wallace and Mike Wallace. As a child, Wallace’s boisterous behavior earned him the nickname “Herman,” after a mischievous cartoon character named Herman the German. Earlier this season, Wallace was voted in by fans to compete in the NASCAR Nextel All-Star Challenge at Lowe’s Motor Speedway. Wallace has already tasted victory on dirt this season, beating O’Reilly USMTS competitor Steve Arpin at the Volusia Speedway Park in Barberville, Fla., in February, and, most recently, winning a UMP Modified feature at the Peoria (Ill.) Speedway on May 23.

The rugged road warriors of the O’Reilly USMTS will be led into battle by Fertile, Iowa's Kelly Shryock as the current national points leader seeks his unprecedented ninth crown. Other drivers expected for these barnburners include Zack VanderBeek, Jason Hughes, Al Hejna, Tommy Weder Jr., Scott Green, Corey Dripps, Jon Tesch, Jason Krohn, Tommy Myer, Mike Spaulding, Dean Mahlstedt, Mark Noble, Mike Hejna, Richie Gustin Jr., Ryan Gustin, Jeff Schluetter, Donovan Lodge, Brad McEwan, Alan Mondus, Scott Vesely, Joey Schaefer, Steve Wetzstein, Brian Shaw, Brad Pinkerton, Dan Bohr and more!
