Five racing cars, eight drivers, plenty of horsepower: in 2025, Canadian racing team JMF Motorsports launched into its first GTWCA race season. With STAHLWILLE as its new official tool partner, the team celebrated some notable successes. Now the collaboration is entering the next level.
The SRO GT World Challenge America (GTWCA) is one of the most prominent and renowned race series for GT vehicles in North America. In 2025, it welcomed a promising newcomer in the shape of JMF Motorsports. Joining the starting grid with big plans, the team gave its all, went through a huge learning curve, and celebrated a number of successes that exceeded expectations for a ‘rookie’.

Successful championship debut
In the very first race at Sonoma, for example, Mik Grenier and Michai Stephens, driving the Mercedes-AMG GT3 branded with the STAHLWILLE logo and sporting number 34, finished in first place. As the season went on they found themselves standing on the podium every weekend, notching up four wins and an outstanding second place in the championship.

JMF Motorsports also raced two Toyota GR Corolla TCs in the TC America. After a brilliant second half of the season, Jonathan Neudorf claimed second place in the drivers’ championship, with Antonio Constantino finishing fourth. In the team championship, the team finished the season in second place. And last but not least, JMF Motorsports competed in the GT4 America Silver Series with two Aston Martin Vantage AMR GT4 EVOs. In this hotly contested class, the team ended the season in third place in the overall ranking, claiming two victories and a total of eleven podium finishes.

Partners: STAHLWILLE and JMF Motorsports | Series: GT World Challenge America | Vehicle: Mercedes-AMG GT3 | Focus: Precision tools in motorsport
Tools are critical to the performance of a race team. During maintenance, setup, and pit stops, every step needs to be carried out with speed, accuracy, and reliability – often under tight time constraints.
The tools used in motorsport need to be exceptionally tough, durable, and precise. Even the smallest errors can affect vehicle performance or safety.
The key tools used in professional motorsport are precise, durable hand tools. Some of the most important are torque wrenches, ratchets, sockets, screwdrivers, and special tools. These allow the crew to work with precision on safety-related components such as the chassis, brakes, and engine, and make a vital contribution to vehicle performance and reliability.
Motorsport places extreme demands on people and materials. STAHLWILLE uses this environment to test and refine the performance and precision of its tools under real-life conditions.
