DIRTcar 305 Sprint Car Series by Fanatec - 2025 Season 4 Fixed

logo for DIRTcar 305 Sprint Car Series by Fanatec
2025 Season 4 Fixed - Races every hour on the hour
The Fanatec 305 Sprint Series, featuring the 305 winged sprint car, is the perfect series to learn the art of open wheel dirt track racing. With 450+ ponies on tap, there’s no shortage of power and, with a Texas-sized wing overhead, theres lots of "bite" - aka downforce - to keep you planted on the dirt. That's not to say you can't get the 305 sprint car plenty sideways; in fact, if you’re not sideways at least half of every lap, then you’re just not trying hard enough. But the combination of power and grip is just right for newcomers to sprint cars eager to sink their teeth into iRacing’s catalogue of legendary dirt tracks.
