41 different drivers competed during the year, tying the all-time record from 1996 at the time, but only six drivers started all twelve races, with three others missing two or less events. Former Indy 500 starters Jon Herb and Tyce Carlson competed at the Freedom 100.
Other teams that expanded to a full-time effort were Michael Crawford Racing, AFS Racing and Dave McMillan Racing, although the latter scaled back during the year. The series had 16 to 18 cars at most of his rounds, with 19 starters at the Freedom 100, but only 11 at Milwaukee and 14 at the Sonoma races.
