K&N Pro Series East
Gdovic first tried his hand at K&N Pro Series East competition in 2011, running 11 of the series 14 races. Running for his father and with funding from Aquis Communication, he scored one top five finish and three other top tens on the way to a 15th-place points finish. Gdovic failed to finish only two races. In 2012, Gdovic ran the entire season, recorded a career-best third-place finish at Greenville-Pickens Speedway, other top fives at Richmond International Raceway, Langley Speedway, and Greensville-Pickens, and recorded top-tens in all but five races. With only one crash on the season, he finished seventh in season points. 2013 led to Gdovic's first win, at Greensville-Pickens. He also recorded a second at Richmond and a third at Bowman Gray Stadium, but three engine failures in a fourteen race season dropped Gdovic to tenth in series points. The team scaled back to part-time in 2014, with only one top ten finish and three crashes in eight races. While focusing on the Lamborghini Super Trofeo series in 2015, Gdovic made only one start, a 12th at Virginia International Raceway.
