In 2022, Holzem made his car racing debut, teaming up with twin brother Juliano at Dörr Motorsport in the ADAC GT4 Germany. The season yielded little success, as a twelfth place during the final race at the Hockenheimring meant a 40th place in the standings for the Holzem brothers.DTM
For the 2023 season, it was announced that Holzem would progress to the DTM with Project 1, entering the championship following an extensive testing programme and guest starts at the GTC Race and the ADAC GT Masters, the latter of which Holzem together with Marco Wittmann would score a podium in. Following his DTM debut at the Nürburgring, ADAC officials granted Holzem full entry to the series, subsequently enabling him to score championship points.Racing record
