The IMSA GT4 Sprint Series, presented by Grid Finder, is a fixed setup GT4 championship on iRacing open to drivers of all skill levels. Compete in some of the most iconic GT4 machinery on the planet across six action-packed events, with the championship decided by your cumulative points total at the end of the season.
Each event follows a consistent format: a single qualifying session sets the grid, followed by three sprint races of equal length. Points are awarded across all three sprints, rewarding consistency as much as outright pace. Full series rules and regulations can be found here.
Cars
Choose from six eligible GT4 vehicles — the Aston Martin Vantage GT4, BMW M4 GT4, Ford Mustang GT4, McLaren 570S GT4, Mercedes-AMG GT4, and Porsche 718 Cayman GT4 — all running under iRacing's Balance of Performance with a fixed setup issued for each round.
Prizes
The top three drivers in the championship standings will receive IMSA prize packs. The highest scoring driver at each event takes home an IMSA die-cast model, with one additional model raffled among all participants. Full prize details are outlined in the competition regulations.
