Shift Up Now Athletes Erika Hoffmann, Ashley Freiberg and Loni Unser announced today that they will be racing for Kellymoss in the 2026 Pirelli GT4 America season.
Erika Hoffmann, a Porsche Sprint Challenge rookie standout, is teaming up with Porsche Sprint Challenge USA West Cayman Pro-Am champion Jack Parriott to join the GT4 America grid. Parriott's strong progression and racecraft have demonstrated his readiness for a new challenge, while Hoffmann continues to build good momentum early in her professional career.
“I am incredibly grateful for the opportunity to compete in GT4 America with Kellymoss this season,” Hoffmann expressed. “I love this team and I’m thankful to be back with them for 2026. Continuing with Porsche while moving into open competition is an exciting challenge, and I’m looking forward to growing as a driver throughout the season.”
In the Silver class, Porsche Female Driver Program representatives Freiberg and Unser are joining forces and making their return with the highly recognizable Be Your Own Hero livery. Intentionally designed to resonate with young fans, the livery’s impact extends beyond the track through a dedicated merchandise line in which one hundred percent of proceeds are redistributed into diversity initiatives to help grow the sport for future generations.
Notably, Freiberg claimed the 2023 Porsche Sprint Challenge 991 title, and advanced to the Porsche Carrera Cup North America championship last season. As she pursues this next endeavor, Freiberg enters the season backed by longtime partners Mobil 1, Radius Drive, and WOW Carwash. Meanwhile, Unser secured third in the Porsche Sprint Challenge Cayman class standings in 2024 before going on to finish as vice-champion in 2025.
“I’m truly honored and excited to be racing with Kellymoss this season alongside Loni Unser,” exclaimed Freiberg. “Loni and I have worked together for several years through Radius Drive, and it has been incredibly rewarding to watch her hard work translate into such strong performances in the Porsche Cayman GT4 over the past few seasons. I’m looking forward to competing alongside her and building on that momentum together.”
“Victoria Thomas has been an incredible source of support and inspiration for me, and I’m grateful for the opportunity to join her and the entire Kellymoss crew for what promises to be an exciting season in SRO GT4 America,” she continued. “We’re putting in the work this off-season and are committed to showing up prepared, focused, and ready to compete at a high level. I can’t wait to get started.”
"When you want to be the best, you have to surround yourself with the best,” stated Unser. “That's why I couldn't be more excited to race for Kellymoss for the third year in a row.”
“What excites me about this lineup is the balance,” stated Andy Kilcoyne, Principal and Chief Technical Officer. “ Each pairing is very intentional. We have drivers continuing to sharpen their racecraft, stepping into deeper manufacturer competition, and aligning in ways that accelerate one another’s growth. That combination creates a powerful environment for development."
The 2026 Pirelli GT4 America season takes place across a total of 13 rounds at seven different venues, kicking off at Sonoma Raceway on March 26th - 29th.
