Your sim racing is in good hands
Hi, I’m Luis, founder of BoxOneRacing.
I’m a sim racer myself.
BoxOneRacing is built from real sim racing experience.
I started developing my own Button Boxes because I couldn’t find products that combined the functions, materials and tactile feel I wanted for my own setup.
Today, we develop, manufacture and assemble our products ourselves in Southern Germany.
That means we stay close to every product we ship and to the people using them.
From sim racers. For sim racers.
Over 5000 SimRacers Drive with BoxOneRacing
