Ronnie Vajdak is a club-level driver who raced in NASA, a multiclass national championship mixing amateur and professional entrants on the same grid. He drove in two classes, Honda Challenge 2 and Super Touring 5, across three seasons from 2021 to 2023.[1]
Vajdak took 13 wins and 17 podiums across 23 starts in NASA. He finished 21st in the 2022 championship standings, the highest championship position recorded in his career on file. The bulk of his success came early; his most recent season, 2023, consisted of three rounds raced.[2]
