Geoff Isringhausen Jr. retired after a single season of racing in 2023, competing in International GT. His record was exceptional for a debut campaign; he won five of twelve rounds and finished on the podium in all twelve races, securing the series championship with an average finishing position of first place. His Racer Rating of 2,461 reflects competitive strength within his field.[1]
Isringhausen dominated his most frequent rivals across the season. He finished ahead of Maria Mejia in all ten races they shared, and ahead of Kevin Maxim in eight of nine encounters. He won every head-to-head against Quirt Smith and Rick Iorio. His record against stronger drivers was selective but notable; he defeated Steven Thomas, a former champion and FIA Bronze-graded professional, in all three races they contested together. He also beat drivers rated higher than his field average, including Silver-graded Michael Johnson and Tom Long, though these victories were isolated rather than part of an extended pattern.
International GT fields a mixed grid of amateur and gentleman competitors alongside occasional drivers with sportscar grading credentials. The series sits in the middle tier of North American sprint racing. Isringhausen's complete sweep of the podium and his decisive championship suggest he was the dominant driver in the field that year before stepping away from racing.
