Kube GmbH Ingenieurbüro is delighted to announce that it will now be supporting Janne Stiak from the Target Competition team in the Porsche Sixt Carrera Cup Germany as an official partner.
At just 18 years of age, Janne Stiak can already look back on a remarkable motorsport career: he first got behind the wheel of a car at the age of 12, practised his first drifts on secure test tracks and completed his first kart race shortly afterwards. His first racing experiences in the ADAC North German Kart Cup quickly followed.
At the age of 13, he takes to the racetrack: Janne completes his first laps in a BMW touring car on a racetrack in France and tests a Porsche GT3 for the first time in 2021. Two years later, at the age of 15, he makes history: he becomes the youngest driver ever to make his debut in the Porsche Carrera Cup on the legendary Spa-Francorchamps circuit in Belgium
After promising results in his first season, Janne celebrates his first victory in the Porsche Sixt Carrera Cup Germany at the Sachsenring on 8 September 2024 – becoming the youngest race winner in the series. In 2025, he makes a strong statement with another success in Zandvoort. These achievements underline his extraordinary talent and his ability to deliver top performances even under the highest pressure.
For Kube GmbH Ingenieurbüro, this cooperation is a special milestone: with his sporting successes and passion, Janne embodies the very values we stand for – excellence, precision and innovative strength.

In addition, we are thrilled with Janne’s career to date and the ambition and discipline he has shown in taking the next steps in motorsport. We want to support him in the best possible way and are very much looking forward to working with him.”

The next race weekend is just around the corner: Janne Stiak will be back on the grid at the Sachsenring on 23 and 24 August. We’re keeping our fingers crossed for him and wish him every success!
