Why choose BSR?


With more than 2 decades of professional racing experience, and engine development, we have just the right know-how to inject a bit of speed into your life. We are experts who enjoy transferring our experience from the racetrack to your car, so that you get more out of your driving. In our test lab, deep in the forests of Småland, our engineers are hard at work developing Tomorrow’s products to maximize your engine to world class quality, tailored to your car.

Each and every product that we develop for your engine, is tested both on the road and individually. Each undergoes the so-called Rototest to ensure the precise effect before and after tuning. We guarantee that nothing other than the car's performance is affected. Onboard computer, traction control, calculations of service intervals, torque limitations in the transmission and other settings are not affected when you tune your car with one of our products. That's why our tuning kits come with a machinery warranty.

When you choose BSR, you can feel safe knowing that you are guaranteed a product that is of the highest quality and specially developed for your car by the pros.
