The speedway at Irwindale has expanded its 2013 lineup of racing events to include three 'spec' classes, according to Irwindale Event Center GM Bob Klein.
Klein announced that 15 more individual race events had been added to the track's 2013 NASCAR calendar, including:
"Bandos" are full-bodied, steel-tube-framed, mini-race cars powered by a 570cc / 30-horsepower Briggs and Stratton "Vanguard" engine that employs a centrifugal clutch to transmit power to the rear wheels.
* The S2 division, set up as the step between Karts or Legends Cars and full-size stock cars.
The S2's are a touring division, and fans will see them at Irwindale twice this season: on April 27 and again on July 20.
* The Southwest Tour Trucks will compete in five events at Irwindale this season: May 4, August 31, September 21, September 28, and October 19.
The Southwest trucks combine a much-modified GM "metric" chassis with a tube frame upper section; they cover that frame with a replica pickup truck body rendered in fiberglass, and power the machine with a closely controlled V-8 engine.
