Four divisions will compete on the third-mile clay oval at Bakersfield Speedway on Saturday night, but the big attraction will be the annual pre-Fourth of July fireworks show.

Tradition for the past several years has been to hold a fireworks show before the Fourth of July and then take the first Saturday in July off, giving racers a break right around the holiday.

The 15-20 minute aerial display is set to light the sky around 9:15 p.m. with plenty of racing action before and after.

IMCA Modifieds, Street Stocks, Hobby Stocks and American Stocks will be in action.

Hobby Stock drivers will be taking part in the second-annual Richie McGowan Memorial 32, with a total purse of $3,200.

Chad Johnson is the runaway point leader in Hobby Stocks and has won three races. He is the only driver with multiple wins.

Larry Hood and four-time winner Brad Pounds are locked in a tight battle for the IMCA championship.

Matt Lewis leads the American Stock points race.

Racing starts at 6 p.m.

Late Models at Kern Raceway

David Mayhew will be looking to continue his winning ways Saturday night when Late Model stock cars return to action at Kern County Raceway Park.

Mayhew has won four of the six races at the paved half-mile oval and leads Eric Richardson (one win) by 12 points. Brian Richardson (one win) is third in points and will be back in his own car following repairs from an accident a few races back. He had been dirving a borrowed car.

Other drivers expected include: Gary Elmore, Jason Small and Johnny White.

Also in action will be Spec Mods, Mini Stocks and Mini Dwarfs.

Chris Dalton has raced to victory in both previous Spec Mod features with Johnny Wood and Billy Lay each having a win in Mini Stocks.

Racing starts at 6 p.m.

New class on horizon for KCRP

A tentative rules package has been put together for the new Street Stock-type division at Kern County Raceway Park. Rules will be unveiled today at the Action Auto Sales yard at 1430 S. Union Avenue at 7 p.m. All drivers interested in participating are encouraged to attend.
