Stephen Vajda is an amateur sportscar driver competing in IMSA's Mustang Challenge and Pilot Challenge series. Graded FIA Bronze, Vajda has made 26 starts across both series since 2020, all with NV Autosport, accumulating three podium finishes from 22 Mustang Challenge races between 2024 and 2026. His Racer Rating of 2,271 places him among drivers competing at amateur and gentleman-driver level in GT and endurance racing.[1]
Vajda's record against regular rivals shows a consistent gap to stronger competitors. Against three former champions rated in the professional range, Zachry Lee, Alex Bachoura, and Neil Verhagen, Vajda finished ahead in only five combined outings across 35 races. His head-to-head record with Tom Tait, a similarly graded Bronze driver, is notably unfavourable at 7 wins versus 15 losses across 22 shared races. His average finish of P7.8 reflects his typical standing in amateur-level grids. Vajda has finished ahead of drivers graded at the professional level on isolated occasions; he beat FIA Gold-rated Elliott Skeer twice and Adam Adelson twice, though these remain outlier results rather than a competitive pattern.
Vajda remains active in 2026 Mustang Challenge, where he has completed two rounds this season without reaching the podium.
