Aitken brings with him a record of success in regional and national karting competitions and now steps into open-wheel racing as he begins the next phase of his motorsports career.

Zanella Racing is pleased to confirm a fifth driver for the final two events of the 2025 USF Juniors program with the addition of Florida kart racer Rahim Alibhai for Road America and Portland International Raceway.

The doubleheader weekend delivered mixed fortunes, but both drivers showed grit and growth on the 2.258-mile road course in their best finishes of the season. Brendan finished in the top-10 in both races, including a season-best fourth in Race 2, while Kaylee scored a ninth in Race 2 after being driven off track in the opening race on Friday afternoon.

14-year-old Belgian talent Karel Staut continues his remarkable progress in the USF Juniors Series. At the second round of the season, held at the legendary Barber Motorsports Park in Alabama – one of the most technically demanding circuits on the calendar – the young driver once again proved why many insiders see him as a future front-runner.

At just 14 years old, Belgian racing prodigy Karel Staut is turning heads on the international motorsport stage. After a highly promising debut at the USF Pro Championships Presented by Continental Tire in New Orleans, the young talent is eagerly anticipating the next three rounds, set to take place from May 1–3 at Barber Motorsports Park as part of the prestigious INDYCAR event weekend.
