Great American Stockcar Series 2018 Event Schedule

This year the Great American Stockcar Series (GASS) will be racing in NW events at Portland International Raceway (Portland, OR) , Sonoma Raceway, or Thunderhill Raceway Park with expanded eligibility to increase car count at every event!

GASS has expanded their eligibility requirements to include nearly all fiberglass bodied stockcars*. All stockcars will qualify for starting position and race as one group, but be scored in two different categories, based on engine horsepower (410HP). Please refer to the rules for the Unlimited Competition Class and 410 Class.
