MADELINE STEWART Lands 3-Year IMSA Deal With WeatherTech Championship Goal

December 24, 2025

• MADELINE STEWART secured a three-year deal with Czabok-Simpson Motorsport starting in 2026, giving the 25-year-old Kiwi the stability and strategic planning that’s often missing for women drivers trying to climb the ladder. The partnership includes a clear progression pathway to the IMSA WeatherTech SportsCar Championship by 2028 – the kind of long-term vision that actually builds careers rather than just filling seats.
• Stewart brings serious Porsche credentials to CSM, having spent two seasons in Porsche Carrera Cup North America and being part of the Porsche Mobil 1 Female Driver Program. Her 2025 season showed real progress with eight points-scoring finishes in the final nine races, proving she’s not just maintaining position but actually developing speed when it matters most.
• The deal positions Stewart in the GS class driving a Porsche Cayman GT4 RS Clubsport, while CSM enters its third Michelin Pilot Challenge season with clear ambitions to be front-runners. Both sides emphasized the commercial and strategic development aspects alongside the racing – because we all know talent alone doesn’t pay the bills or secure the next opportunity in this sport.
