USAC 360 Sprint Car Series - 2025 Season 4

2025 Season 4 - Races hourly at :15
The iRacing USAC 360 Sprint Car Series is a great introduction to non-winged sprint car racing but with "only" 720 horsepower on tap, not quite as fast or furious as the 410 sprint cars of the iRacing AMSOIL USAC National Championship. Make no mistake, the competition is no less fierce and the tracks are the same as those run by the 410s. But with a few less ponies hooked-up to their throttle pedals, newcomers can learn the ropes of classic dirt sprint car racing while still go plenty fast enough to get -- and keep -- their attention.
