Frankie Muniz wins GT4 America championship with co-driver Tyler Stone

The 2026 GT4 America season came to an end with a double-header weekend at the Indianapolis Motor Speedway road course. Actor-turned-racer Frankie Muniz was in position to win the championship, skipping multiple NASCAR races where he is a full-time Truck Series driver to chase the crown with co-driver Tyler Stone. They entered the weekend with just one point over their closest competition, but a pair of runner-up finishes was enough to secure them the Am class title by 19 points over James Walker Jr. and James Clay.
