Your sim racing is in good hands
Hi, I’m Luis, founder of BoxOneRacing. I’m a sim racer myself.
I started developing my own Button Boxes because I couldn’t find a product 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 keeps us close to every box we ship and the people who use it.
From sim racers. For sim racers.

Try it on your rig for 60 days
Use the box in real races, feel the buttons and encoders, and see if it fits your rig.
If it isn’t right for you, you can return it within 60 days under our Test Drive Guarantee.
