Polestar 2 suspension, BST edition 270

What was the brief?

Based on Polestar’s specific performance targets, three suspension spring variants were initially engineered for the BST Edition 270. 

To accelerate development, Polestar brought a test vehicle to our Swedish manufacturing facility, where a dedicated live workshop was established to support hands-on collaboration.

What happened next?
The limited BST edition 270 Polestar 2 performance suspension springs were installed and evaluated on various road surfaces surrounding the factory. Performance data was continuously monitored, and analyzed as steering response and suspension behavior were assessed. Suspension settings were then fine-tuned through close collaboration between Polestar and Lesjöfors engineers.

After the suspension spring design was agreed and development milestones met, the Polestar BST Edition 270 test car was taken to Spain for high-speed testing. The testing revealed that the suspension setup was slightly too stiff.

Rydholm explains: “When you do a project like this, in your heart you need it to be perfect.” The drive showed it wasn’t perfect. As Joakim freely admits, he had to make one of the most difficult decisions in his life. The new Polestar BST edition 270 suspension spring was ready at Lesjöfors, but the test drive had shown that the spring needed adjustment. Rydholm says: “Here I was, knowing that I had given Lesjöfors an almost impossible deadline which they had met, to then make a call from Spain explaining that the springs needed to be modified once again. The ride height and stiffness needed to be adjusted. Incredibly, Olof and his team understood everything across our ride heights and spring stiffness, designing a new suspension spring and manufacturing to the new requirements, shipping it out to Spain the next day. It has to be said, when you call from the test track and ask the springs to be 5% softer and they come the next day – that’s customer service.”

With the adjusted springs installed, Joakim completed an intensive week-long validation drive, from +20 °C at Barcelona’s proving ground to –25 °C in Northern Sweden. The route covered dry asphalt, heavy rain, ice, and snow, validating the suspension system’s performance across extreme temperatures and varied road conditions.

Building on the intensive development work and engineering insights gained from the Polestar BST Edition 270 suspension springs, customers can now order an optional performance pack for the Polestar Performance model. Manufactured by Lesjöfors, the kit includes two front suspension springs and two rear, forming a complete Polestar 2 lowering springs package that delivers a driving experience closely aligned with the BST configuration.

Working in close collaboration with Polestar, activities were aligned across all project functions to ensure the spring solution met the performance requirements within a demanding timeline. The result was a successful, cross-functional development project spanning engineering, manufacturing, and validation.
