A potentiometer would need some sort of leverage reduction to remove the forces (50kg would physically crush a potentiometer!). The benefit aside from dealing with very high forces associated with the brake pedal is the mechanical aspect of the overall pedal design can be simpler. Unlike, say, a potentiometer you can put very high loads through a load cell, measuring the force as an electrical signal that is then amplified in the pedal electronics. What are load cells, and how are they used in pedals?Ī load cell is also known as a “ force transducer“. Better control and easier manipulation of the car are all done through the pedals, and in such a competitive environment, it’s OK to want to exploit every potential advantage there is. In my humble opinion, a pedal upgrade can be the most significant update you can make on your racing rig. I always advise a sim racer looking to start upgrading their rig: go for the pedals first. PSA: If you’re upgrading for the first time: go for the best pedals first The electronics get quite sensitive the further up the development (and cost!) spectrum you travel, but the benefit of this is that you can notice just how fine your control is over the simulated environment. They also, critically, have the electronics onboard to measure the input on the throttle, brake and clutch with load cells. Generally speaking, you’ll find in “high-end” sim racing pedals that the components (and the mechanical design of the units) tend to handle the kind of brake forces you’d expect in a real racing car.
