Over the next three months, Atlanta Motor Speedway will be the epicenter for race fans, competitors and automotive enthusiasts as one racing series enters its third week and another prepares to launch.

Between the Thursday Thunder weekly racing series and the Castrol GTX Friday Night Drag Racing Series, more than 4,000 drag cars, Legends cars, Bandoleros and Thunder Roadsters are expected to hit the AMS asphalt this summer.

Celebrating its 10th season, Thursday Thunder, a 10-week Legends racing series will take place every Thursday night from May 31 to August 2, with a special Wednesday night edition on July 4 featuring a fireworks extravaganza. Drivers ages eight to 68 compete on the "Thunder Ring," AMS' paved frontstretch quarter-mile oval.

Featuring a full slate of competitive racing, as well as concourse activities, intermission spectacles and grandstand games, Thursday Thunder is an affordably-priced activity that offers something for spectators of all ages. Tickets are just $5 for adults and $1 for children 6-12 (children under 6 are free) for each evening of family fun and grass-roots racing.

Atlanta Motor Speedway launched its newest form of racing when the 12-week Castrol GTX Friday Night Drag Racing Series kicked off on May 11, 2007.

The series is open to any automobile and any driver, provided they possess a valid driver's license. The competition will be heads up, street-style drag racing on AMS' one-eighth-mile pit road drag strip. A simple points system was installed for 2007 with division champions crowned at the end of the season. Three points will be awarded for a final round win with two points awarded to the runner-up. A single point will be awarded to every participant.

In addition to the pavement-pounding drag action, a Show N' Shine car show, held in a garage on the AMS infield, will feature collector vehicles divided into five classes, with trophies and plaques awarded to the top-three finishers in each division.

All racers must have a valid driver's license and competitors age 16 and 17 must have a fully executed minors release form on file at the speedway prior to competition (forms available at the speedway or at www.atlantamotorspeedway.com). Competitors must wear a helmet and have operational seat belts in the vehicle and pass a pre-race safety inspection.

The 2007 Castrol GTX Friday Night Drags Series will run June 1, 8, 22, 29, August 3, 10, 17, 24, 31 and September 7. Gates open at 7 p.m. and practice drag runs begin at 6:40 p.m.  Show N' Shine car show judging ends at 8:45 p.m. with the championship drag runs starting at 9:10 p.m.

Both drag and Show N' Shine competitors entry fees are $20 while spectator admission is only $7.
